Game modes

In QuakeWorld there are different game modes to play by. All the classic mods were famous in QuakeWorld, such as Capture the Flag, Team Fortress, Clan Arena, RocketArena, even Cooperative mode... But nowadays Deathmatch mode is dominant.

Most QuakeWorld servers today are Kombat Teams Extreme servers (KTX). KTX supports multiple mods, and on most servers you can change which mod to play, on the fly. Refer to webpage for more info.
For example, to select the desired game mode on a server that supports it you may type 1on1, 2on2, 4on4 etc. That will load the default configurations for the selected game mode.

The few servers that don't run KTX run other mods, but these are dedicated to a specific mod, and you can't change it. For example FFA, CTF, Teamfortress, Coop... have their own dedicated servers. You can filter the available servers on QuakeServers.net.
