It appears that Superman is indeed real and is currently residing in Battlefield 3, however he seems to picked up the far more conventional knife as his weapon of choice.
All that’s missing from this video is the Superman theme – which is apparently coming according to the uploader. The perfect moment where you hear, “here’s your ammo,” and then he’s gone, knife to the back. Players pull off some astounding things in Battlefield 3, and this is certainly another to add to the pile. Not only does a knife make you run faster (if you’ve never played Counter-Strike you probably won’t understand) it also lets you fly.
