I have a Surface 2 and it has been great all week long.... until I tried to play Halo: Spartan Assault. The game runs great but it overheats my Surface. The back gets REALLY hot (which doesn't bother me) and then the screen automatically dims to the lowest level. At this point is unplayable. I basically have to wait until it cools down to start playing the game again. Has anyone else had this problem? I'm hoping its just a problem with my machine and I an exchange it. Please help!
