An unfinished but near full-featured 7.5GB sized version of Gears of War 3 has leaked onto the Internet over the weekend. According to a poster on the website NeoGAF, the leaked build of Gears of War 3 includes the full single-player campaign and all the multiplayer options. The game will only be playable on a modified 'JTAG' version of the Xbox 360.  It is also said to be very buggy at the moment. The game isn't due out until September 20 and is considered perhaps the biggest exclusive for the Xbox 360 this year. Naturally, Epic is working hard to try and contain the leak, or at least punish those that are responsible for it, claiming it is working closely with their security teams and law enforcement to address the situation. The company was also quick to assure that the leak does not represent the experience players will have with the real thing.

Update:Epic told GameSpot that the footage released by those with the development build of the game is not from the current game build, and is also not accurate to what the current build offers. Their wording was as follows:
 
"We have seen the reports of Gears of War 3 content being propped on the web and [we are] working closely with our security teams and law enforcement to address the situation. This content is not from a final build and is not representative of what fans will enjoy when the game launches worldwide on September 20, 2011".
