I've put together and worked on a bunch for Insurgency. All in my Github at
https://github.com/jaredballou/insurgency-sourcemod
I have done:
-Rework of Brutus' logger to include class/team changes, updated weapons, more events.
-Bot names replaced with more appropriate Middle Eastern names
-A compass that pops up a simple "N" or "SW" as a Hud hint by command for players to know where they're going
-A navigation mesh parser that loads all named zones (I'm working with some people on the Insurgency forums to update the navmeshes and navplaces.db for all the maps)
-Support for Simple Chat Parser, includes translation file
-SCP addon that prepends grid location and place name (if navmesh has them) before team chat messages
-Plugin that removes fog entirely
-Plugin that removes all restricted areas entirely
They're all pretty straightforward, I'll probably add a few to the plugins forum once I've got them polished up a bit more, but I'd be happy to have you check it out and get me some feedback.
