Rescue

Summary
Rescue was a gamemode in Left 4 Survival and is a counterpart to Survival. This gamemode is prove to be difficult for Survivors due to one of Infecteds are somewhere that overpowered.

Mechanics
This gamemode is different to Survival as the rescue vehicle can appear one location in any maps. The rescue vehicle has 5 minutes to appear and survivors must get to it to win while zombies need to stop them. Once the rescue vehicle appears, it takes 45 seconds (estimated to be 15 seconds shorter than that it should in Reason 2 Die Awakening) to depart. If all survivors die or they are not in rescue vehicle while it leaves, the zombies win.

Survivors

 * Never camp on the location that rescue vehicle lands like the tall building in Construction Site, as Riots can charge you off the landing area which kill you quickly by fall damage if not keep moving.
 * If a rescue vehicle appears, do not immediately go to it.
 * This can allow zombies to damage you which kill you if not throwing a pipebomb.
 * Try to wait until 0:10 timer, then immediately rush to the rescue vehicle to win to trick the zombies.
 * This can be countered by Tanglers by dragging you immediately by and Hunters lunging you quickly and by Chillers by freezing you right away before it's too late.

Zombies

 * If a survivor waits until 0:10 seconds which rush towards a rescue vehicle, remember to grab them immediately as Tangler, freezing them fast as Chiller and lunge quickly to them as Hunter before it's too late.
 * When a rescue vehicle appears, camp on the rescue vehicle to prevent survivors from getting to it if they are on low health.
 * This can be countered by using a Rocket Launcher or throwing a Pipebomb.
 * In the tall building in Construction Site, Riot can work well, as it can charge towards a survivor which kicks them off the area, killing them by fall damage. Take advantage if any survivors camp to wait for the rescue vehicle to appear on that map.
