Just thought i let you guys know that v 8.4 of garry's mod has been leaked. It's not too much different then the current version but meh. I guess one of his gold members released it.
It's not fake, it does include a game creation scripting thingy(LUA), the ability to add wind, and motion blur. That's about it. The LUA scripting is really cool, just a bit complicated if your going to make your own scripts. and no its not an old version of v7a. It's version 8.4 beta 004.
