Perimeter is a sci-fi arena defense game — hold the generator against a small, smart raider
squad across escalating waves. Need help, found a bug, or have a suggestion? We'd like to
hear from you.
Fastest way to reach us: email
nsuemml@gmail.com — include your device model and
iOS version if you're reporting a bug, plus what you expected to happen, and we'll get back
to you as soon as we can.
Why do enemies ignore me and attack the generator? That's the core
mechanic, not a bug — the raider squad prioritizes the generator over you whenever it can
reach it. Position yourself to block their path in.
How do upgrades work? After each wave you pick one of three upgrade
cards. Runs are short (6–10 minutes), so experiment freely between attempts.
Where is my progress saved? Locally on your device only — there's no
account and no cloud sync. See our Privacy Policy for
details.
Does this game need internet? No — Perimeter works fully offline.
How do I reset my progress? Settings → "Reset all progress."
