Valve have revealed the fourth game mode for upcoming co-op zombie shooter and it goes by the name Scavenge.

Scavenge is made up of a series of rounds, in which up to eight players try to move gas canisters to a specific point on the map with a generator, all while a team of people control Infected trying to put an end to the proceedings.
