Perimeter: Outpost Survivor

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 — a small, capped raider pack that reads the battlefield, picks off the objective when it can, and only turns on you when you're the thing standing between them and it. **Outnumbered doesn't mean outsmarted** A handful of raiders, not two hundred — but every one of them is a NavMesh agent with a target priority: you, then the generator, then your perimeter fence. Watch them peel off mid-fight to flank the side you left open. The tension isn't "can I out-DPS 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 mobile-first UI throughout. **Build a run in 1-of-3 picks** Clear a wave, choose one of three upgrade cards, and watch your loadout snowball — unlock the carbine, stack fire rate, armor the fence, whatever the run demands. Every run reshuffles the choices; every run plays differently. **A boss built from your own defenses** Reach the end of the escalation and face the Perimeter Guardian — the station's own decommissioned defense drone, captured mid-raid and turned against the outpost that built it. **Six minutes, one more try** Sessions run 6–10 minutes across 15–20 waves. Die or win, you're back at the class-select screen in seconds — no loading screen standing between you and the next attempt. **Your progress, your device** No account, no sign-in, no cloud sync required to play. Runs, unlocks, and achievements save locally. **Now available on iPhone.**
