Support

An iPhone or iPad with ARKit world tracking (A12 Bionic chip or newer) running iOS 18 or later. Devices with LiDAR (Pro models) also let real walls and furniture hide enemies behind them.

• Stand a few metres back so the whole doorway, top to floor, is in view, and hold steady for a moment.
• Turn on the lights; dark rooms are hard to map.
• Tap Mark, aim the crosshair at the doorway and place it yourself.
• One door or one floor portal is enough to start. The game keeps scanning while you play.

Floor portals need about one square metre of clear floor, at least a metre and a half from you and away from doors. Slowly sweep the camera over open floor. A bigger room helps.

Move the phone slowly, keep the room well lit and point at textured surfaces rather than blank walls. If it gets confused while scanning, tap More → Restart tracking.

• Both players need the app and an account (Sign in with Apple, Google or email), and must be in the same room.
• In a game, tap the call-for-help button and send the invite link, or ping a recent helper.
• Your friend opens the link, taps Join the Fight, then points their camera around the room to sync with yours. Allow Local Network access when asked; the devices connect over Wi-Fi and Bluetooth.

Stand close to each other and scan the room slowly from where the host scanned it. If it still fails, tap Retry; the host's phone sends its room again.

The pistol and shotgun are free. Every other weapon is unlocked with coins in the Armory (main menu, or between waves). You earn coins for every kill and every cleared wave, and they also buy damage, magazine and reload upgrades. There are no in-app purchases.

Coins, unlocked weapons and upgrades are saved on your device, so deleting the app removes them.

Settings → Account → Delete Account. This permanently deletes your account and its data. See the Privacy Policy for details.

Settings → Blood & Gore: High, Low (the default) or Off. Off shows sparks only.
