What is JCoopZ?

The coop gametype running this server traces back to JCoop4/JCoop5 by Joss Liu, one of the original Unreal coop mods. When JCoop5 stalled without a finished release, developer Zombie (of DZ) got permission from Joss Liu to continue the project, rebuilding much of it from the ground up with years of stability and security fixes along the way. It was eventually renamed JCoopZ to mark it as its own branch, distinct from a parallel continuation done by other community developers around the same time.

Chat & identity

say <message>
Talk to everyone. Spam and repeated messages get filtered automatically.
setname <newname>
Change your display name. Might not work if the admin has restricted name changes or you've changed it too often already.

Voting

mapvote [#slot]
Show the map vote list, or vote for a specific slot to be the next map. Only works if the admin has map voting enabled.
voteend [yes|no]
Vote that you're ready for the current level to end. Once enough players agree, the server moves to the next map at the end teleporter.

Quality of life

getid
Shows the current player list along with each player's game ID number (same ID shown on the scoreboard).
help [command]
Lists the available commands, or shows more detail for one specific command. Genuinely the most useful command on this list.
shotsquelchall
Ignore shots and hits from other players. Handy if someone's being annoying and keeps knocking you around.
suicide
Respawn if you're stuck. Limited number of uses – the server will warn you as you approach the limit.
How to use these: Open the console (usually ~ or Tab) and type the command directly. Anything starting with admin requires being logged in as an admin first – those commands aren't listed here since they're not meant for regular players.
