Hold the generator. The raiders don't want you — they want it, and they flank to get there.
Every wave, pick 1 of 3 upgrades. 15+ waves, one boss.
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.**
