Here we have a nice little Gears of War 3 wallpaper to get you in the mood for the upcoming multiplayer beta. As you can see, the image is pretty similar to the recently revealed boxart only without the huge ass Gear of War 3 logo.
Below you will find links to the wallpaper in a selection of sizes, all of which are in the 16:10 aspect ratio. If you need a different size wallpaper drop a request in the comments and I will see what i can do.
Note, the highest resolution i can make this wallpaper is 2560×1600 which should be big enough for most monitors these days.
