Receiver has been updated with some nice new features like flashlight, Smith&Wesson Model 10 revolver and Glock 17. The weapon reload/safety/trigger hanling is still very realistic and complete.
The game also has been submitted to Steam Greenlight, you can vote for it here: http://steamcommunity.com/sharedfiles/filedetails/?id=92927535
And last but not least: the Unity3D project source code is now available on github: https://github.com/David20321/7dfps
