The briefing

Everyone gets a side. Only one keeps it.

  • Defend your sideYour wall is the only thing between you and out.
  • Last one standingWalls fall one by one until a single side is left.

Up to 20 in the arena. No download, no account — send a link and everyone's in.

Before you buy

When do I get it?

The phone apps are days away. You get a receipt straight away, and nothing else to keep or do — we have your email. The day the build ships we write to you, and that email is where you choose Steam keys or phone unlocks for each copy you bought and pass the spares to friends; Steam keys follow the day the Steam build ships.

Do I need an account?

No. Pay with Apple Pay, Google Pay or a card — your email address is the whole system.

Can I play right now?

Yes — free in your browser, on a phone or a laptop, with as many friends as you can round up. A pack is for what's coming, not for getting in.

Backed on Ko-fi before there were tiers? You're already a Super Founder — nothing to do.

See you in the arena.
