Quake 2 Map Info is a command line utility that parses a Quake 2 map file and reports how many entities and textures are being used. It is useful for spotting extra items to improve gameplay balance and/or reducing extra textures to increase map speed. Most map editors do not provide a detailed breakdown of what is inside a map. It is compatible with any Quake 2 (ID Tech 2) game engine if the map file format has not be altered. If a game has a different map format, you can modify the source code to reflect the new format.
GibCounter is an application that parses QuakeWorld fraglog files, generates human-readable global and per-player statistics, and writes them out in an HTML format. it supports graphical percentage bars, frag-per-death ratios, and colored "fun nicknames". The appearance of any element of the generated stats can be easily changed through a CSS include file.
YAWn! Linux is a client for the YAWn! service, which keeps track of the names used by players of "Return to Castle Wolfenstein". Players are tracked by their unique PunkBuster GUID, and thus players cannot hide behind a fake name to play recklessly or purposely misbehave. YAWn! adds a console command to "Return to Castle Wolfenstein" that lists all players like PunkBuster does. However, this command also displays the other names that the player has used before, or (for players that use YAWn! themselves) the name and taunt-message that the player chose at registration.
