# This pattern has been tested with QuakeWorld (2.30), Quake 2 (3.20),
|
|
10
|
# Quake 3 (1.32), and Half-life (1.1.1.0). But may also work on other

|
11
|
# games based on the Quake engine.

# Counter-Strike: Condition Zero, and the game Day Of Defeat, Team

# Fortress Classic, Deathmatch Classic, Ricochet, Half-Life [1] Deathmatch,

# and I imagine all the other 3rd party mods that also use this engine

|
18
