Overdose is a good name, because you gonna OD on how much this game abuses you patience with its terrible levels and enemy types custom made to be as annoying as possible.

you gotta ask yourself, how on earth did they saw a game as simple and mindless as the original Gungrave and fuck it up by trying to "outdo it", without noticing their own limitations at all.

also, don't believe the credits, Tsuneo Imahori didn't make any music for this, 80% of game is dead silent.
