Outbreak
Hold the line
Round-survival. The horde arrives in waves that never stop getting bigger, the guns are on the walls and you have to pay for them, and half the building stays dark until somebody finds the breaker.
The loop
You start with a pistol and 500 points. Everything after that you buy.
Earn
Ten points a hit. Sixty for a kill, a hundred for a headshot kill, a hundred and thirty for a melee kill or for reviving a teammate. Ten every time you nail a plank back onto a window.
Spend
Wall weapons from 500 points; re-buying ammo for a wall gun you already own costs half. The mystery box costs 950 and gives you something you did not choose.
Open up
Debris gates cost points to clear and turn the map from one room into a route. Which gates you open decides where the horde funnels.
The power switch changes the map
Wall weapons, the mystery box and the debris gates all work in the dark. The perk machines and the upgrade machine do not. Finding and throwing the main breaker is the moment the run stops being about survival and starts being about a build.
Perks
Eleven perks, four at a time, all of them lost when you go down for good. Every machine needs power.
| Perk | Cost | Effect |
|---|---|---|
| Ironhide | 2,500 | Four zombie hits instead of two. |
| Fasthands | 3,000 | Reload and swap far faster. |
| Marathon | 2,000 | Sprint further, recover quicker. |
| Hellfire | 2,000 | Fire rate up on everything you carry. |
| Second Wind | 1,500 | Get back up faster when a teammate reaches you. |
| Galvanize | 2,000 | Melee hits far harder. |
| Packhorse | 4,000 | Carry a third weapon. |
| Deadeye | 1,500 | Headshots hurt more. |
| Crashpad | 2,000 | No fall damage. |
| Revenant | 2,000 | Come back on your own once, without a teammate. |
| Doppelganger | 2,000 | Keep your loadout through a death. |
Costs are the shipped values. Effects are summarised for readability — the exact numbers are in the game.
The Forge
5,000 points, and the power on
Feed a gun into the Forge and it comes back with double damage, half again the magazine, double the reserve — and a new name. A Ranger SMG comes out as a Ranger Ascendant; a Vantage Rifle as a Vantage Sovereign. The rename is how you know at a glance whose run is further along.
And the gun that is not on any wall
One weapon exists only in the mystery box: Gravewell. It launches an anchor, and where it lands it opens a gravity well that takes the horde off its feet. It is weighted to come up roughly once every nineteen rolls — often enough that feeding the box is worth doing, rare enough that it stays the reason you feed it.
The horde
Six per round plus three for every round elapsed, capped by how many can be on their feet at once. They spawn nearest whoever is closest — the horde funnels toward you, not toward the middle of the map.
Walker
The baseline. Slow, weaves as it closes, and there are always more of them.
Runner
Twice a walker's pace and it lunges the last few metres. The reason you keep a corner behind you.
Crawler
Comes in under the sightline you are holding. Slow, quiet, and easy to miss.
Brute
Three times the health, hits half again as hard, and does not stagger the way the others do. Worth a hundred points if you can afford the ammunition.
Stalker
Fast, frail, and it hits quicker than anything else in the horde. Deals with campers.
Drops
Resupply, Overkill, Double Points, Reinforce, Cataclysm and more. Cataclysm clears the board and pays everyone; Reinforce nails every barricade back up at once.
Three ways to play it
Survival
Co-operative. Everyone against the horde, for as long as you can hold.
Grief
Two human teams on the same map, racing. You cannot shoot them. You can absolutely open a door for them.
Turned
One player is the survivor with a full loadout. Everybody else is the horde, hunting them — and whoever brings the survivor down takes the crown.
Custom lobbies can also start you at a later round if you would rather skip the quiet part.
Survivors
Coming in Season 1
Outbreak will get its own cast: eight named survivors whose passive comes out of who they were before this happened, rather than being chosen off a list. A field medic revives faster because she was a field medic.
Where it stands today: that roster is not in the current build. Outbreak is currently played with the Multiplayer operator bodies, and everyone has the same passives. The survivor cast, the separate Outbreak currency and shop, and the mode's own ranking ladder are all Season 1 work. See the season plan →
Where you play it
Outbreak runs on maps that author a real horde layout — boarded windows, buy stations, a power switch and debris gates placed by hand. It is never scattered across a Multiplayer arena that was not built for it. The dedicated Outbreak maps are rebuilding right now, so today's rotation leans on the dual-mode maps.
