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 has 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-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 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.
