We just deployed a 400mb update to the game in anticipation of launch. This is not the final release candidate, but pretty darn close. So please play the game and help us identify and resolve the outstanding issues for Wednesday's release.
You can find the full changelog here: http://www.playinsurgency.com/forums/topic/3121-getting-closer-update-january-20-2013/
Some notable additions and changes include a radial voice command menu, including orders issued by the squad leader with waypoint icons, all new sounds and fixed [AMAZING] distant sounds, brand new Mk18 carbine weapon for Security team, and various tweaks.
Thanks to everyone for your hard work in testing and giving us feedback on the game! The response is overwhelmingly positive, so keep up that momentum for us! See you in the servers :)
