Scavenge Mode

"Haul ass and get gas!"

Scavenge Mode is a new Competitive gameplay mode in Left 4 Dead 2. It is a round based game in which Survivors attempt to find up to 16 gas cans to fuel up a generator (or car), while fighting against player-controlled Special Infected much like in a Versus game. Players can choose the amount of rounds they want to play before the game starts. The Survivors spawn next to the generator and will have 30 seconds to set up and grab their supplies, while the Infected find locations to spawn. The timer will start and the infected will spawn as soon as the set-up time runs out or if a survivor leaves the designated area around the generator. Once the game starts, the Survivors have 2 minutes to find the gas cans, with an additional 20 seconds added for each can they bring to the generator. When the time runs out or all the survivors are incapacitated, the teams switch sides. Overtime will occur if the time limit runs out, but at least one survivor is holding a gas can. During overtime, the survivors will have a limited amount of time to fuel the generator. If all the gas cans are dropped, the survivors turn is over. When the teams switch sides, the previously Infected will become the Survivors and will have to get one more gas can than the previous team to win the round and end it. If both teams collect the same amount of gas cans, the team who did it faster wins the round. The game will end as soon as it is impossible for the loosing team to win. (For example: a game of 3 rounds ends as soon as a team wins 2 rounds.) The team that wins the most rounds wins the game. So, a game is not based on the total amount of gas cans collected in the game. In other words, a team can win even if, overall, they collected less gas cans (as long as they win more rounds).



Gas cans have a white aura, so survivors can see them anywhere on the map. If they are picked up and dropped they will have an orange aura. Gas cans always spawn in the same location on the map. If they get destroyed, they will eventually respawn back at the location they originated. The only infected that can destroy gas cans with its attack is the spitter. However, the attack only works if the gas can has been previously pick up and dropped. When gas cans are hit with the acid they will flash orange momentary, than explode. While flashing, survivors will have time to pick up the gas cans before they exploded. It takes about 2.5 seconds to pour fuel into the generator. However, any damage will instantly restart the pour timer, so a survivor must not be under any attack in order to completely the process.

Tanks and witches do not spawn in scavenge mode.

There are currently 6 maps to play on in Scavenge Mode. The maps are mostly identical to the areas in chapters they are made from, however, they have been modified to block off certain areas to limit the gameplay area, Like the maps in Survival Mode. The area around the generator where survivors spawn usually contains 3 Tier 2 weapons, pills, adrenaline shots, grenades, an ammo pile and at least one melee weapon. Other supply is scattered around the maps, usually near gas can spawns. Supplies like the chainsaw, grenade launcher, Ammunition Upgrades, First-aid kit, and Defibrillator only spawn on certain maps or are not featured in scavenge mode. The amount, the location, and the types of supplies always stay the same on each map.



Infected

 * After set up time ends, don't be to eager to spawn. The survivors may go to an area nowhere near where you were planning to spawn.
 * In Scavenge Mode it isn't just about killing the players. If the timer is low, preventing them from grabbing a gas can with constant non-lethal attacks can help end the survivors turn.
 * Try to focus your attacks on survivors either carrying or pouring the gas cans. Any type of attack by an Infected will reset the pour timer for a Survivor. If a lone Survivor is pouring a gas can, get over to them to pounce, pull, charge, or ride them. This will not only delay the pouring, but make them drop the can. This is particularly important in overtime, because the instant the gas cans are dropped, the survivor's turn ends. The basic special infected claw or punch attack will also delay pouring (though it does not make the player drop the gas can).
 * Spitter acid will also delay a playing from fueling the generator (though it does not make the player drop the gas can). Make sure to spit a few seconds before they reach the generator. This is because it takes a short amount of time for the spit to travel and when the spit hits the ground, it takes a little bit more time to spread, before it does any damage.
 * If the opportunity sticks, go for any survivors that are by themselves and very far away from both the rest of the survivors and the generator, whether or not they have a gas can.1 of 3 beneficial things can happen. Either they'll stop fueling and help the survivor, they'll ignore the survivor and let them die, or a single survivor will come to the rescue, giving an infected partner the opportunity to grab another lone survivor.
 * Many gas cans are enclosed and hard to reach or see from most spots. These are good areas to camp in case a lone survivor comes by to grab a gas can. One place is the back of the bridge in the Motel level, where a fence blocks the gas cans and survivors can only go one way to get the gas cans.

Survivors

 * Don't try to put fuel into the generator when you are being hit. Any damage will instantly restart the time it takes to empty a gas can, so it is best to kill any infected attacking you first before you put the fuel in.
 * Always have at least 1 other survivor near you at all times.
 * If you discover a spitter is on the map, make sure to kill her ASAP. She can destroy gas cans and delay pouring fuel into the generator.
 * If available on the map use long range such as the combat rifle. There are not that many common infected on the map, so using a longer range weapon is better suited for killing special infected, especial if they can move survivors far away from the group.
 * The Throw Down Method
 * This method only works on maps with areas near, but higher than the generator like the Mall Atrium and the Motel.
 * 2 survivors will go around the map and collect gas cans and throw them down near the generator, while 2 other survivors will stay near the generator to fuel it.
 * The collectors should use long range weapons, so they can assist the fuelers if they get attacked.
 * When acting as a collector, try to space out the gas cans thrown, so the Spitter has a harder time destroying them.
 * On certain areas of the map, the throw down method may not be as effective as just carrying the gas can all the way to the generator.
 * If the first survivor team collected less than 3 gas cans, the throw down method may not be necessary, depending on the map.
