SourceCraft

This is a mod I found on Team Fortress 2 a long time ago, unofficially called SourceCraft.  Like most mods on the source engine it uses SourceMod.  There are not many mods like SourceCraft, namely because it's a member of a group called Jiggly's Fun House by the name of Naris.  This mod is based of the War3Source mod, that already adds a few abilitys such as damage boosts and some castable skills, and adds much more to it. The most extravigant ability is seeker projectiles (Rockets/Arrows/Pills/Needles/and Flaming Tampons) but you shouldn't have to worry about them too much (well, unless you come across one of them kids that had mommy and daddy pay for all their levels).  Other special abilities include flying sentries, the "bubble of doom" and just the general ability to seemingly 1-hit any person regardless the situation.  At any rate I hope you give this mod a try and enjoy it as much as i do.
