SourceMod Anti Cheat, v1.2.1.7 (Formely Kigen's Anti Cheat)
Information:
While Kigen has decided to leave the Allied Modders community and drop support for Source Mod in general, there's little reason for his plugin to disappear with him. Development and maintenance of his plugin will be taken over by anyone who wishes to contribute to the project, and as such, the plugin has been renamed to SourceMod Anti Cheat.
