Scavenge Mode

Scavenge is a gameplay mode announced for Left 4 Dead 2. Each game consists of the Survivors and Infected competing against each other to achieve a goal. The Survivors' goal is to find 16 gas canisters hidden in the map and bring them back to a generator, using the gas as fuel. They have 2 minutes to find the canisters, with an additional 20 seconds for each canister they find, before they lose. The Infected team's goal, much like any versus match, is simple: kill the Survivors as fast as you possibly can. It's highly suggested that the Survivors watch their aim when firing at Infected to avoid accidentally setting off the gasoline into a burning inferno. At the same time, this can be used as an advantage for the Infected team as the Spitter has the ability to ignite gas cans with her acidic phlegm.
