Hold the room as survivors
You start with little and look for more. Firearms, explosives, and improvised melee weapons are scattered around, ammo runs short, and every bullet has to count. You push a cabinet against a doorway, nail boards across it, and take positions while one friend watches the corridor with a rifle.
Survival mode tests how long your group can scavenge and stay alive. Objective mode gives you jobs: find keys, restore power, hack a computer, then get to the chopper. Hardcore mode turns the same idea tighter, with tougher foes and a timer. When the boards crack, you press panic and run.
Hunt them as the undead
The other side is played by people too, which keeps rounds unpredictable. As a zombie you move fast, use night vision in dark rooms, and look for a gap in the defense. The carrier can infect survivors, who may not notice at first and can later turn against their own group.
That slow shift in numbers is the whole tension. One survivor falls and joins the hunt, then the barricade that felt safe starts to feel thin. Custom maps and community servers add traps, basements, and odd layouts, so ambushes play out differently each round.
What should co-op friends know?
How do survivors and zombies play differently?
Survivors rely on guns, explosives, melee weapons, and barricades, plus scarce ammo and medicine. Zombies rely on speed, night vision, and numbers, with the carrier able to infect survivors and weaken the group from inside. Rounds often swing as fallen survivors return as zombies.
What do you actually do in objective mode?
You move through the map as a group, searching for keys, restoring power, hacking computers, and reaching extraction. It rewards splitting roles: someone carries, someone covers, someone watches the rear. Fail to finish the jobs and the horde catches up.
How do you pick a side?
Many maps use a physical lobby area where you walk through the door for survivors or zombies. It doubles as a safe place to learn movement before the round starts, and it keeps idle players out of the match until they choose.
Can you play with custom content?
Yes. Community servers and Workshop add-ons supply custom maps, modified rules, and unofficial modes made with AngelScript or SourceMod plugins. Server browsers often list which setup each server runs, so check the name and rules before joining with friends.
