[4-2-2-5-3] Game Type

Single Player: This is the standard story-driven experience where you play alone, facing enemies. It's the only mode that allows saving/loading and using console cheats without modifying game files.

Multiplayer: Players can host servers for competitive matches, primarily Deathmatch. Maps can be designed for multiplayer or be adapted Single Player levels. In these adapted levels, AI enemies are removed, weapons and ammo are more plentiful, puzzles are pre-solved (keys are unnecessary), and level exits are marked with rings to prevent accidental entry. The main goal is to 'frag' (kill) other players for points. Self-inflicted deaths or deaths by level design result in a point deduction.

Cooperative (Co-op): This mode is essentially a multiplayer version of the Single Player campaign. Players assist each other against Quake's enemies. If a player dies, they respawn but lose a point from their score, avoiding the need to reload a save.
