Up to eight players (four Survivor and four Infected) are pitted together in an awesomely violent battle for that most important of resources: gasoline.
Cunning gasoline delivery (picture 1) and pitched battles (picture 2) are a part of Scavenge mode.
The Survivors must scour the map looking for Fuel Cans, collect them and return to a central generator (or car) to pour the gas in. The Special Infected, meanwhile, are out to stop the humans by any means necessary.
After the first match, the sides swap, and the first human team becomes Infected, and the zombie team becomes Survivors. After a set number of rounds, the team with the most Fuel Cans collected and poured into a generator are deemed the winners.
