When I entered the code, it said I'd won an EA Prize. I then got to choose from several different EA games, including, but not limited to, Medal of Honor, Mass Effect 2, EA MMA, The Sims 3, Battlefield: Bad Company 2, Skate 3, etc. All of the prizes only worked for 360 or PC. Don't know why there was no love for PS3, but oh well. I went with Mass Effect 2, seeing as it's the only game out of those that I own. I was then given a screen where I could pick a prize. For Mass Effect 2, I could choose between a visor/nightvision goggles that gave me +5% to Power, a Recon helmet that gave me +5% weapon strength, or another visor/goggles that gave me some other +5%.
I chose the helmet.
