1. Small Star to Black Hole Progression
The concept behind reaching the Black Hole stage as quickly as possible, forgoing the options of building up a multi-star system or 10 planet solar system, is to rapidly consume as much planet mass as possible. The method behind doing so is much like in the Planet stage with some key differences.
Gaining mass as a Star
Instead of now capturing asteroids to consume for mass you will need to capture planets, while more sparse, are easier to capture than asteroids are for planets. This is mainly due to their slower relative speeds compared to your star and the gravity well you possess than can be used to capture them effectively.
Life Planets will of course offer the most mass upon consumption but can be beneficial by also shielding your star while you go about growing larger. You will need at least 2 Life Planets with at least 3 turrets on each before the shield becomes active over your star.
Finally the one important note is that keeping your solar system small will allow you to find more free floating planets as growing a large solar system will cause larger objects like yours to spawn and less smaller objects like lone planets. Also make sure you don’t spawn a second star by consuming too much asteroid mass on one of your planets, unless going for the betrayal achievement below.
2. Betrayal Achievement
Shown in the video below, the process in unlocking the Betrayal achievement in Solar 2 is much the same as growing a single star system to a black hole but just takes twice as long to do. Mass consumed is always evenly split between your stars with whichever one is the smallest having the priority in consuming the next planet. In other words there is no way to turn a neutron star into a black hole while you still have a Small Star or other smaller star as it will consume all the planets you eat until it is of equal size or larger.
One other challenge besides just having to consume more mass is the additional Life Planets you need to maintain a shield around your stars. A good way to determine how many life planets you need for Star Shields is to take the number of turrets currently on all your orbiting planets and divide that number by 6 and round it down. The number you get is the maximum amount of stars that can be shielded meaning 12 turrets across all your planets are required for a dual star system shield.

3. Solar System Building
Building up a solar system in Solar 2 follows similar concepts put forth in the guide covering the progression from Small Star to Black Hole, however instead of simply consuming planets you now want to raise them to fully experienced Life Planets or turn them into additional stars.
Managing The Planets In Your Solar System
As mentioned previously, capturing planets is much like capturing asteroids (check the Planet guide for details and diagrams) requiring you to move so that your relative speed with the planet is 0. Unlike asteroids and planets however, you can capture new planets outside of the first 5 orbit rings up to the outermost 10th as your system grows.
Small Planets will need to be either replaced or grown into Life Planets to start providing real benefits towards your solar system. To grow the planets you will have to maneuver your system as they orbit your star(s) in order to capture asteroids like how you have done before, although now with a slightly different movement pattern needed. Don’t bother trying to grow large asteroid shields around your planets as unless you have their orbits rigidly controlled, their paths will eventually cross each other resulting in smashing your own planets and asteroids into each other.
On your path to grow your solar system and enrich its lifeforms with experience you will be also working towards the Overcrowding achievement which requires you to gain the most life you possibly can in a solar system. This means at least 2 stars and all 10 planets with 18+ kills of experience each, or visually, 4 turrets on each.
Once you’ve managed to grow 10 planets with life on them from consuming asteroids, the best bet to raise their experience and unlock Overcrowding at the same time is to find smaller systems to pick on. Stay a decent range away so your spacecraft engage the hostile spacecraft but cannot reach the enemy planets in order to destroy them outright. Eventually your planets will build up experience in this manner and if you have a couple lagging behind, you can maneuver them so their turrets come into play, guaranteeing that planet makes the kills it needs.
For Supremacy you will need to continue the work you started with Overcrowding, however here we can use physics options (confirmed as this is how I unlocked my Supremacy achievement) to turn up the settings for the max turrets and max ships that planets will spawn while making their build time instant. This should give us planets with 14 turrets each and hordes of spacecraft constantly streaming outwards. Find a nearby enemy solar system to farm like before and in no time you will have racked up 100 kills on at least one of your planets.

4. Brethren Missions 1-3
The Brethren series of missions in the video game Solar 2 have you working as caretaker of the universe, looking after planets that need your protection in order to convert them to your way. All three missions have different strategies to use, however having dual star or tri-star system with max life saved as one of your spawnable systems will be helpful.
Brethren Mission 1
For this mission you will need to protect a target planet that has no life on it. In order to do so, spawn your max life system, consume one of the planets and pick up the target planet, preferably within one of your inner orbits to keep it protected. All you need to do is keep it alive for 60 seconds while asteroids fly at you from all directions. With this method you can pretty much stand still, maneuvering slightly to pick up some of the roids to gain mass on the target planet.
Brethren Mission 2
For this level you need to take your solar system and at least 4 Life Planets through an obstacle course, reaching the target beacon without colliding with any objects whatsoever, beyond spaceships or their lasers and missiles that is. The best way to do this is take your time and travel with 4 planets only to avoid dealing with a wider berth more prone to collisions. Completing this level with 10 planets will grant you a special congratulations.
Brethren Mission 3
Finally in the third mission its time to sacrifice your followers to the celestial gods. In this case you will need to take 6 of your orbiting planets and drop them into the nearby Black Hole. Spawn your max life system before picking this mission up and work your way from the outer orbits inwards. Once you get to orbit 5-6 however, gravity begins to endanger your stars, so it's a good idea to pick some new planets up after dropping off the first 3-4.

5. Duel Missions 1-3
The Duel missions are part of the Star and Solar System Stage in the game Solar 2, meaning you will need to spawn yourself as either a Star or Solar System in order to pick up and complete the missions successively. If at any point you move to another stage, be it respawning as a planet or advancing to a Black Hole, you will forfeit the mission and have to restart.
The Duel missions in Solar 2 will have you facing off against progressively larger and more dangerous enemy solar systems which you must completely demolish in each level to proceed onwards. The strategies are pretty much the same for each mission but the differences in what you are fighting will be listed below. Also, for those of you who have already pulled off the Grind Star achievement, there is a special method you can use here.
Level one has you fighting against a single Medium Star with 6 orbiting planets all starting with 3 turrets.
Level two has you fighting a Large Star with 8 planets all starting at the 3 turrets experience level.
The last mission pits you against a Tri-Large Star system with 10 planets all at full experience. Quite the challenge indeed.
Tactics for these Missions:
Generally your best bet here is spawning your max life system and fighting it out by plowing your stars into the planets orbiting the enemy solar system until you have an upper hand. Once you have at least 2 more planets than the enemy system, your life should slowly start to overrun the enemy, hastened further by continual physical strikes to the planets and the stars once their shields are down.
If you have completed and saved your Grind Star system:
If you have one of these super star systems from unlocking this achievement, you can literally just sweep over the enemy to complete these missions practically instantly. If you’re going to do both, do this achievement first to cut down the time it takes you to blast through the Duel chain.
"Hobo Star" Achievement
Start the 3rd part of the "Duel" mission as a single star with no planets and beat it in under 3 minutes.
To unlock the Hobo Star achievement you will have to beat this mission starting as a single star with no planets. To perform the Hobo Star task effectively, you should be a Large Star with as much possible mass before hitting neutron star, then use your star to knock the planets orbiting this system into the stars itself. Once you drop the system to 4-5 planets, you can steal some of them to give yourself a shield and continue plowing the targets.
Remember, you only need a sliver of shield up to stop all damage from a collision so once you have shields up, make your hits hard against other unshielded targets. Finally you will have to do this in under 3 minutes to unlock the Hobo Star achievement. Alternatively you can try to use your gravity well to propel the enemy solar system into other objects but this can be hit or miss depending on what spawns in the area.

6. Heist Missions
The heist missions in Solar 2 now have you tasked with some interstellar thievery on behalf of the Entity, eventually culminating in a mad dash from the cops. These levels pose unique tasks in each mission with different strategies and two separate achievements to unlock in these levels, I Got this and Get Lost.
Heist Mission 1
The first level of heist has you stealing a target planet from a single star system that has no other orbiting planets. Using a almost max life system, you will want to knock that planet out of orbit using one of your own and quickly evade the massive waves of Nomad ships that erupt from all corners of the screen. To complete this level normally, just run from the Nomads and make it to the target mission beacon with the swipe card planet intact. See below for how to get the I Got This achievement.
Heist Mission 2
In the second level you have to capture 3 enemy planets from other solar systems and maintain all three in your orbit at the same time. This was originally 4 planets at once, as you will see in the video, however this was changed with a patch to 3.
Heist 3 + "Get Lost" Achievement
This mission is one that is actually harder to complete without earning the achievement Get Lost. To complete this mission normally, you have to navigate what is a stream of two lines of stars that create a curving path that you must navigate as it gets progressively smaller and more challenging, without touching the sides. Personally I have not been able to finish the mission this way.
However, to unlock the Get Lost achievement and complete this level in an alternative and far easier way, start the mission using an at least Tri-Star system with preferably max life. Immediately as the mission begins, head either up or down right off the bat to break through the Star wall that forms, which should decimate your system but if done fast enough, will leave you at least somewhat intact on the other side, unlocking Get Lost. See the video below for this achievement.
Heist Missions Video Guide
"I Got This" Achievement
To unlock I Got This, you will need to complete level one by destroying all the attacking Nomads before making it to the mission beacon. The first easiest way to do this is by plowing through the Nomads with your system, taking care that the swipe card planet is orbiting on the opposite side of the direction you’re headed in to keep it safe from weapons fire. The second option to clear the Nomads for I Got This is to lead them to a nearby hostile system with tons of life that will eventually whittle away and destroy your aggressors. See the second video below for this achievement

7. Invader Missions
The invader levels in Solar 2 are somewhat similar to the Nomad Love missions you faced as a planet, this time around facing larger amounts of forces that come in waves. The strategies for these group of missions is the same for each, with the only difference between the levels being a progressively larger amount of ships to deal with.
Generally speaking, you can spawn as a max life solar system, which you should have saved from use in the other missions and solar system building walkthroughs, and just duke it out with the aliens that attack you using your lifeform spaceships and turrets.
One important tactic is to always move around when a new wave shows up, as they typically gang up on a single one of your planets. You want to dart around to break up the attackers and get them interested in your spaceships versus your planets to avoid losing the extra life spawned by it. You can also try to get them interested in any nearby hostile solar systems or Life Planets. Other than that, the tactics here are pretty simple and straightforward.
*This mission group is part of the index due to its relative simplicity in explanation.

8. Final Boss
Upon completing all the various missions available to you in all 3 primary stages of Solar 2, Star, Planet and Asteroid, you will be presented with one final mission by the Entity. Your last task will be facing your ominous director, celestial power versus celestial power, in your hardest challenge yet. Completion of this mission and witnessing the video it rewards unlocks the achievement The Entity in the video game Solar 2.
The Entity, whom you must now destroy, consists of 7 Medium Stars chained around 2 Black Holes. These stars will constantly spawn planets which they will then fling out at you after a few orbits and the Black Holes will cause a massive gravity well that will pull in everything nearby.
In order to perform this mission successfully, you will have to spawn as a Star or Solar System and complete the entire mission without advancing to the Black Hole, or you will forfeit the level. Completing this mission also results in unlocking The Entity achievement.
Tactics for the Boss Mission:
The idea here is you want to use a system with multiple stars and max life to give your stars shields with which to plow into the Entity’s stars after knocking lose their Life Planets. If your shields drop and you lose mass, remember you can retreat for a bit to capture the planets thrown off by the entity and grow your stars back up. Once 6 stars have been taken out, the final one will get consumed by the Black Holes and The Entity achievement will unlock along with a brief video.
If you have a Grind Star system saved from the achievement below, you can use it to sweep over the entity’s own stars much like mentioned for the Duel missions. Just be careful not to lose too many of your own stars in the Black Holes during your passes.
"Final Boss" Video Guide
9. "Elite" and "Grind Star" Achievements
Both the Elite and Grind Star achievements are free-form tasks that can only be completed during the Star stage of Solar 2. Both are closely related, with Elite requiring you to build up a 6 star system and Grind Star requiring a 40 star system.
One point of note is that these achievements can both be unlocked with physics or god options on and this is exactly what we are going to do to quicken the process. Depending on which version of the game you have, it may be necessary to complete all the main game missions in order to unlock these options first, which is suggested since doing this task without these options is guaranteed to take a very long time.
Options to Set
Gravity Factor = 0 (This will be changed later, but it helps initially)
Collision Damage Factor = 0
Instant Spawn Mode = Key Down
How to Build Your System:
With collision damage turned off and the ability to instantly spawn both planets and asteroids we will be able to make our system grow to phenomenal sizes at a quick rate. What you need to do is hold down the C key to spawn planets until you have 10, then hold down the Z key to spawn an endless supply of asteroids which you will move your planets through while repeatedly tapping the L key to absorb all the rocks captured.
With this method you will quickly hit the 6 stars needed for the Elite achievement and as your progress towards 15 and up, will want to turn gravity up a bit while moving around more as the asteroids will start to spawn inside your ring of stars, requiring you to dance about to fling them outwards towards your planets.
Remember to always spawn additional planets once one has been turned into a new small star. Also remember to save your system along the way and once more upon reaching the 40 stars needed to unlock the Grind Star achievement, as having a massive star system can give you a unique method to completing some of the missions.

10. Star Challenge Missions
Star Challenge Mission 1: "Dark Dodger"
The Dark Dodger star challenge mission will have you as a Neutron Star, tasked with staying within a large circle drawn in space while waves of dark matter asteroids are spawned near you non-stop. It is up to you to dodge and survive these rocks as much as possible, at least 35 seconds needed for the hard score, realizing that a single impact will spawn a black hole that will suck in and destroy your star.
Easy Score: Survive for at least 15 seconds.
Medium Score: Survive for at least 25 seconds.
Hard Score: Survive for at least 35 seconds.
These challenge isn't as difficult as it may sound, as for starters in Dark Dodger the asteroids are spawned slowly and with little to no beginning speed. The one factor working against you is the massive gravity well of the neutron star that will constantly pull them towards you. As a helping hand, the path function is forced on in this mission, allowing you to move opposite of the oncoming asteroids direction while evading collisions with them. Keep in mind the asteroids will stay within the circle and the challenge is made progressively harder by their increasing numbers, although some may collide with each other and absorb one another at the same time. Don't stop moving and stay as far away from all of them as possible to limit your gravitational pull.
Star Challenge Mission 1: "Dark Dodger" Video Guide
Star Challenge Mission 2: "Getaway Again"
The Getaway Again star challenge mission in Solar 2, as its name suggests, is a repeat of the Getaway star story mission with a new twist to have you facing off against. You will need to complete the entire course while taking as little damage as possible as a large star. Note: You cannot escape the course to complete this mission as you can do with the story version, you will have to take the difficult route and navigate the entire course to succeed.
Easy Score: Less than 1500 damage taken.
Medium Score: Less than 500 damage taken.
Hard Score: Less than 150 damage taken.
If you have already completed Getaway, you will actually find this challenge a little bit easier in some respects, considering the course itself is somewhat easier to navigate. However the challenge here comes with avoiding damage. Your best bet is to not worry so much about asteroids, avoiding them when possible, but soaking up the hits when dodging them may otherwise cause you to collide with something larger. Since the damage of asteroids is only 1 per rock, you can soak up at least 149 asteroid hits without facing failure or denying you the hard score. As long as you can avoid the stars themselves, you will be fine here, however if not, a single high damage collision with one can mean failure. The path key will help you predict oncoming paths, and remember to utilize and watch out for the effects of both your gravity well and that of the star lane.
Star Challenge Mission 2: "Getaway Again" Video Guide
Star Challenge Mission 3: "Snowball Fight"
The Snowball Fight challenge mission is a special challenge added for the 2011 Steam Winter Sale as one of the gift grab games, with the associated achievement Snowflake Star which unlocks for players earning at least 4 points, or the medium score for this mission. The idea here is to take your star with 8 orbiting, lifeless snow planets, and fight a duplicate of your system by smacking your snow planets, or snowballs, into the enemy star without taking hits yourself. Each hit you take reduces your score by 1 and hits you make on the enemy increase your score by 1. The mission ends when either system is devoid of its snowballs.
Easy Score: End the challenge with at least 2 points.
Medium Score: End the challenge with at least 4 points.
Hard Score: End the challenge with at least 6 points.
In Snowball Fight and the achievement Snowflake Star, you can earn up to 8 points by completing the round perfectly by smacking all your snowballs into the enemy star without taking any hits yourself, or losing a snowball by hitting one of the enemy's planets with one of your own. Snowball to snowball collisions cost and earn you no points.
The enemy star is completely motionless, allowing you to navigate in between its orbiting planets with your own, although will begin to move if drawn in by your gravity well and close presence, so avoid hovering around it to much to keep it from flying across the screen. Take your time, since there is no clock or timer here, and wait for the orbits of both system's planets to make your hits easier, keeping in mind to avoid any strays. If you haven't already, it helps to get an idea of how orbits work in Solar 2.

11. Multi-Star Challenge MissionsClick thumbnail to view full-size
Chaos Duel Challenge
Chaos Duel has you spawned as a twin star, with a full solar system consisting of evolved life planets with physics options turned up for both max turrets and max lifeforms, facing off a similar multi-star system. Your enemy will have an upper hand here, with their stars consisting of 2 neutron stage stars with yours being medium sized. The task here is to destroy the dual stars of the enemy system while surviving, within a set time limit to reach each score rating.
Easy Score: Destroy the enemy system in 3 minutes or less.
Medium Score: Destroy the enemy system in 2 minutes or less.
Hard Score: Destroy the enemy system in 1 minute or less.
The trick with Chaos Duel to quickly overcome the enemy for the hard score, is to start the fight off by blowing your system into theirs. Try to use your stars (preferably) to take out the enemy life planets, or your own planets if you can do so without losing too many, in order to get the star's shields to drop. Once you have a significant life advantage you can allow some of the ships to help eradicate the enemy life bearing planets as well. Once the enemy star's shields are down, with yours still up (hopefully) you can ram the neutron stars directly, detonating them while your star is saved by its shield. Switch to hitting with your second, still shielded star to take out #2 in the same fashion. Once the enemy neutron stars are gone, you win, even if there are life planets left floating through space.
