Nano Breaker

Nanobreaker is a PS2 action game that puts you in the shoes of a cyborg who has been put into artificial sleep and awakened to play the role of a bodyguard. Armed with a plasma sword, your goal is simple: annihilate hundreds of enemy hordes in order to escort a scientist to a research center. The stakes are nothing less than the corruption of a deranged AI and the survival of humanity.
