The two devices cannot find each other

Both must be in the same room with Wi-Fi and Bluetooth switched on. The first time, iOS asks for access to the local network — it has to be allowed on both devices (Settings → Room Battle → Local Network). One player taps “Create battle”, the other “Join battle”.

“Shared map” does not light up

Stand next to each other and look at the same part of the room, preferably one with furniture and corners rather than a bare wall. Move the devices slowly. Good light helps.

Tanks do not hide behind furniture

Full room scanning needs a device with LiDAR (iPhone Pro and iPad Pro models). On other devices only the walls and tables the game detects give cover; the menu tells you which mode you are in.

I bought two-player battles and it is locked again

Tap “Create battle” and then “Restore purchase”. You need to be signed in with the same Apple Account that made the purchase.

Do both players have to pay?

No. Only the player who creates the battle needs the purchase; joining is free.

How do I change the language?

The globe button in the main menu. The game follows the system language until you choose another one.
