Also introduced is the new Scavenge mode, an eight-player mode similar to Versus where the point isn't to reach the safe room it's to collect gas cans and dump them into a generator, the winner determined by which team can get more into the generator before they're overwhelmed.
The game sports a few new features such as three new special infected: the self-explanatory Charger, the acid-puking Spitter, and the body-clinging Jockey. The difference this time out is the setting is located somewhere around the Louisiana area. You play as one of four survivors trying to make their way though bloodthirsty hordes of mutant infected to reach safety. The plot is roughly the same as the previous game: a deadly virus epidemic has claimed the country.
