Troubleshooting
Is this the Half-Life 2 story game?
No. This build only offers multiplayer Deathmatch: players fight each other.
Wi-Fi connection fails
Check that both phones are on the same network and the host’s address is correct. Guest Wi-Fi networks may block connections between devices.
Internet connection fails
Make sure the host is in the game and the room is still open. If entry expires, tap “Renew entry” on the website. If the phones cannot connect, try another network or Wi-Fi mode.
How do I move and look around?
Drag on the left side of the screen to move. Drag on the right side to turn the camera.
Do I need port forwarding?
Normal connections do not require manual router setup. If your network cannot connect the phones, try another network or Wi-Fi mode.
My bug report was not sent
Without a connection, the report stays on your phone and is sent later. Check its status in the same form.
The nickname is taken
Choose another nickname: each player in a room needs a different one. Use Latin letters, numbers, a hyphen or an underscore.
Why is “Join” disabled?
Wait for the host to open the game. The room must also have an available seat.
