1B OutbreakFirst-person shooter for Android
The night is long. Bring a flashlight.
A first-person zombie shooter running on a 3D engine we wrote ourselves. Ten maps, from a fog-drowned cemetery to the city rooftops; thirty missions, with a boss waiting at the end of every map; eleven weapons to upgrade — and a flashlight you'll learn to love. For adults only.

Ten maps. One very long night.
Every map has its own weather, its own light and its own way of getting under your skin. Three missions each, and the third one always ends with a boss.
- 01
Container yard
Stacks of shipping containers under a cold moon, blue-grey haze and sodium lamps.
- 02
Suburb
A dead-end street at sunset: six houses, a crashed bus and a petrol station full of barrels.
- 03
Cemetery
The thickest fog in town — and the dead climb out of the ground between the graves.
- 04
Subway
Almost no light, flickering tubes, red emergency lamps. Down here, the flashlight is the game.
- 05
Hospital
A ring of corridors under sickly green light, with locked rooms you'll wish you hadn't opened.
- 06
Mall
A huge atrium under bluish moonlight, every shop lit by its own neon sign.
- 07
Forest camp
A storm, rain and lightning; the campfire in the clearing is the only warm light.
- 08
Industrial plant
Orange fog, drifting embers and furnaces that spit fire. The place itself is a weapon.
- 09
Sewers
The densest fog of all, green and nearly black. Things drop out of the walls.
- 10
Rooftops
The finale: rooftops linked by walkways, red beacons and a helicopter searchlight sweeping the night.
- 10maps, each with its own weather and light
- 30missions in the campaign
- 6bosses
- 11weapons, each with upgrades
The game contains intense violence and gore and is for adults only (rated 17+/18+, depending on the country) — none of it is shown on this page.

Inside the game
A whole night of content
A full campaign, endless survival on every map and a daily mission — on a 3D engine we wrote ourselves.
01Thirty missions, ten maps
Each map is a place with its own weather and light — from a container yard to the city rooftops — with three missions and a boss at the end. Objectives change: kill, survive, defend, collect, reach, hold and escort.
- Easy, Normal or Hard — Hard opens after the first map
- Stars to earn on every mission
- A briefing for every mission: what to expect, plus a piece of intel
02Bosses with weak points
Six bosses close the maps, each a fight with its own trick: an armoured giant you make crash into walls, a siren behind a shield fed by pylons, a titan whose fire is its armour.
- A boss at the end of every map
- Weak points that take double damage
- Each one beaten with a different tactic
03Every enemy has a tell
Screamers keep their distance and call the horde — take them out first. Ghouls flee from your flashlight. Stalkers hide when you look their way and rush you when you don't. Riot cops wear helmets that soak up headshots until they fly off.
- 13 kinds of zombie and 13 monsters
- Swarms shrug off bullets, but not fire or shotguns
- Elite zombies that shield, regenerate or split in two
04When the campaign is over
Survival never ends, on every one of the ten maps; the classic arcade is still there; and the daily mission picks a map and an objective for the date.
- 11 weapons, each with four upgrades
- 5 perks, ranks up to 30
- 28 achievements
Our own engine, built from scratch
No off-the-shelf game engine and no bought assets: every model, texture and sound is generated by our own code, so the whole game fits in about 9 MB.
- Dynamic lights, cascaded shadows and a flashlight that casts its own shadow
- Volumetric light shafts, fog, rain and lightning, bloom and a colour grade for every map
- 664 sounds, all generated by code
- Quality presets — Auto, Low, Medium and High — and Auto picks one for your phone
- Needs OpenGL ES 3.0; plays in landscape
