Rachel borrows some threads from the Dynasty Warriors crew.

Ninja Gaiden 2 was a real ball-breaker. Ninja Gaiden Sigma 2 is slightly less of a ball-breaker, mainly because the camera system has been slipped a few espressos, but still ridiculously tricky. And that, my friends, is what makes it Ninja Gaiden.

Passing on gameplay tips would be a crime against our medium’s increasingly scant reservoirs of trouser-soiling difficulty. If you’re after an easy life, go tuck into Mini Ninjas. Here are a few pointers on the subject of character unlockables instead.
