Sell PS2 Games. Get Cash for Gungrave Overdose. In Gungrave: Overdose, you once again play Beyond the Grave, a silent one-man army who's equipped with two deadly handguns that can fire round after round without any need for reloading. Grave also happens to have this large coffin chained to him, and he can use it to thrash any foes in his vicinity or destroy any abstacles that stand in his way. This device doubles as a shield and triples as an extremely powerful cannon, which is awfully convenient. Grave is pretty quick on his feet, too. There's a lot of satisfaction to be had in employing Grave's ridiculously overpowered tactics. Grave and his young friend Mika encounter two drifters, Juji Kabane, a blind and embittered swordman, and Rocketbilly Redcadillac, who is perhaps best described by the fact that he fights with an electric guitar. This game in which the abject is to make your way from one end of a level to the other while shooting absolutely everything that moves, and everything that doesnt move, just in case.
