Creates a private lobby with these settings. Invite friends from your list or share your code — everyone readies up, then you start.
Create a lobby, invite friends with your code or a link, choose the map and mode, then start when everyone is ready. Empty slots can be filled with AI.
Enter the 6-character code your friend shares (their friend code is also their lobby code).
Online play uses peer-to-peer WebRTC (PeerJS). The lobby host is the authoritative server for hits, strikes, ammo and scores. Some strict networks block peer-to-peer connections; a TURN relay would be needed there.
Friends add you with your code. Anyone with your link joins your lobby directly.
