New in 1.1.0: a wider camera, a fresh HUD and a mission map with stars. The raiders still go around you to reach the generator. Hold the line.
They're not coming for you. They're coming for the generator — and if you're not standing in
the way, they'll go around you to get it.
Perimeter is a compact arena defense shooter built on one idea: the enemy squad actually
targets what matters. No mindless horde walking straight at you — raiders break in from beyond
the perimeter fence, read the battlefield, go for the objective when they can, and only turn
on you when you're the thing standing between them and it.
**See the whole fight**
The camera sits high above the arena, so you watch the raiders cross the fence and split up
before they reach you. Pinch to zoom in or out whenever you like.
**Outnumbered doesn't mean outsmarted**
A handful of raiders, not two hundred — but every one has a target priority: you, the
generator, the fence. Watch them peel off mid-fight to flank the side you left open. The
tension isn't "can I out-damage this crowd," it's "did I leave a lane uncovered."
**Auto-fire, all decisions**
Your gun handles itself — auto-targeting the nearest threat so you can focus on where to stand,
when to fall back, and which lane to plug. Touch controls and a phone-first HUD.
**Build a run in 1-of-3 picks**
Clear a wave, choose one of three upgrade cards, and spend coins in the shop mid-mission:
unlock the carbine, stack fire rate, add health and ammo — whatever the mission demands.
**Mission after mission**
A campaign map of 12 stages with 8 missions each — from 8 waves early on to 30 at the end,
with swarms, armored squads, ambushes, sieges and elite hunts along the way. Earn up to three
stars by keeping the generator intact and winning fast, then jump straight into the next
mission from the victory screen. A daily task and a personal record table keep you coming back.
**Play in your language**
English, Deutsch, Français, Italiano, Español, Português, Русский, 中文 and हिन्दी — pick one in
Settings and the whole game switches instantly.
**Your progress, your device**
No account, no sign-in, no ads, no in-app purchases. Your progress is saved on your device.
