Infection: Complete Survival Guide

1The clock is the real horde

Infection starts with one or two infected players hunting a full lobby of survivors. Every survivor who falls joins the infected team, so the mode has a built-in snowball: the longer the round runs, the worse the odds get for the living. Survivors win by staying alive until the round timer expires; the infected win by converting everyone.

That structure changes how you should think about every decision. Early round, the infected are weak and slow — the danger is complacency. Late round, the map is crawling with converted players who know exactly where the survivors like to hide — the danger is predictability. A good Infection player has a different plan for minute one and minute four, because the lobby becomes a different species by then.

2Good spots have exits

Where you stand matters more than how you aim. Strong survivor positions share three properties: limited approach angles, a visible sightline toward those approaches, and at least one exit you can take without touching the main entrance. If a position has no second plan, it is just a waiting room with worse lighting.

Places I trust for about two minutes

• ▸Elevated platforms with a single ladder or staircase — you see every attacker before they reach you.
• ▸Corner rooms with a window exit — defendable, but never a dead end.
• ▸Long corridors with a fallback door behind you — you trade space for time repeatedly, which is less heroic than it sounds and more useful.

Rooms that pretend to be safe

• ▸Sealed rooms with one door and no exit. They feel safe until the first infected arrives with friends.
• ▸Open plazas. Nothing limits the approach angles, so you can be rushed from all sides at once.
• ▸Any spot that was great last round. The infected team remembers, especially the teammate you abandoned there.

3Barricades are delays, not homes

Blocks are your most renewable defensive resource. The goal of a barricade is not to be unbreakable — every wall falls eventually — it is to make the infected spend time in a spot where you can see them working. The wall is a timer you place by hand.

• ▸Double-layer the entrance, but leave a one-block gap at eye level so you can watch the break progress and time your exit.
• ▸Build your escape before your wall. A barricade with no exit plan converts a fortress into a coffin.
• ▸Barricade corridors, not doorways. Two walls ten blocks apart in a hallway cost the infected twice the breaking time for the same materials.
• ▸Rebuild behind you while retreating. A single block placed at a choke as you fall back can buy three or four seconds. I have won rounds on less.

4Kiting without feeding panic

When barricades fall — and they will — movement keeps you alive. Kiting means staying just outside the infected team's reach while pulling them across terrain that slows them down more than it slows you.

Loops beat straight-line heroics

Never run in a straight line to a dead end. Plan circular routes: around a building, up one staircase and down another, through a window and back along the outside wall. A survivor on a loop can run indefinitely; a survivor in a straight line is just scheduling their own conversion.

Make the chase useful for somebody else

Keep roughly ten blocks between you and the nearest infected. Close enough that they commit to the chase, far enough that a single stumble does not end your round. Pulling several infected into a long chase is genuinely valuable — every hunter chasing you is a hunter not breaking your teammates’ barricades. The trick is not to drag the whole parade straight through their front door. I have done this. Nobody clapped.

5Converted players should communicate

Getting converted is not the end of the round — it is a role change, and playing it well is half the mode. The infected win through pressure and information, not through solo heroics. Nothing wastes a horde faster than four players chasing four different rumors.

• ▸Spread out to scout, group up to break. Solo infected find survivors; grouped infected finish them. Call locations before you commit.
• ▸Attack barricades in pairs. One breaks while one watches the exit — most kills happen when survivors flee, not while they hide.
• ▸Cut loops, don’t follow them. Against a kiting survivor, one infected keeps chasing while another runs the loop backward to meet them head-on.
• ▸Sacrifice for tempo. Trading your life to force a survivor out of a strong position is a good trade — your respawn is fast and their position is gone forever.

6The final minute punishes stubbornness

The final sixty seconds are a different game. Most of the lobby is infected, the survivors’ positions are known, and the map has been stripped of easy hiding spots. The player who refuses to leave the old plan usually becomes proof that the old plan has ended.

• ▸Go mobile early. If your barricade will not survive the last rush, abandon it at ninety seconds and switch to kiting while you still choose the route.
• ▸Save a block pocket. Three or four blocks placed mid-chase — a step up to a roof, a plug in a window — routinely convert the last minute into a win.
• ▸Use the timer psychologically. Infected get desperate and sloppy in the final seconds; bait a lunge past a corner just before the horn and simply step aside.

7Mistakes that help the horde

• ▸Hiding in a dead end and hoping nobody looks. Somebody always looks.
• ▸Spending all blocks on the first barricade, leaving nothing for the retreat.
• ▸Fighting when you should run. Knockback tools exist to create distance, not to win duels against a growing horde.
• ▸Reusing last round’s spot. Converted teammates carry your secrets to the enemy team.
• ▸Giving up after conversion. Half the mode’s skill ceiling lives on the infected side.

8Infection FAQ

When the barricade falls

Infection is a mode about seconds: seconds bought by a well-placed wall, seconds stolen by a smart loop, seconds defended in a final rooftop stand. The best survivor teams do not stay brave in one room forever. They leave before bravery becomes furniture.
