Resident Evil 5

As well as including the concept of the "las plagas" parasite, this fifth part of the series also brings back the novel gameplay from the previous game. With an over the shoulder view, Chris confronts hordes of infected enemies that can throw objects and even shoot at you. They can be repelled with various guns, grenades, or using the knife and melee attacks if they get too close. This time though, Chris has a partner, Sheva, who accompanies him through all the game and can be controlled by a second player, with both characters having to keep an eye on each other to survive. The second player can enter and leave at any time playing locally through split screen or online.
