Ninja Crusaders

Ninja Crusaders (as the title translates) fight against invading machines in a post-apocalyptic world. The game is unique in that your ninja can transform into different animals. It all depends on the weapon you have at the moment: if you have a shuriken, you become a tiger; if you have a chain, you become a scorpion; if you have a stick, you become a bird; and if you have a sword, you become an unkillable (but time-limited) dragon. The duration of the levels is short, but you are likely to spend a lot of time in them. The thing is that the ninja dies with the first blow. That's why it's not an easy game.
