What're They Running?

Tool to grab information on SRCDS/HLDS servers, including info about installed plugins, via A2S server queries. Results are cached for 10 seconds.
NOTE: Plugins listed are inferred from notify CVars, therefore this is NOT a comprehensive list because many plugins either don't have version CVars or don't set them as notify.
NOTE 2: My list of plugin-CVar associations is relatively sparse right now (total 349, and mostly TF2 plugins) so expect a lot of them to be listed as unknown!
TIP: Some different plugins use the same version CVar. Make sure the version number matches with the version history of the plugin this tool links to.
