Take that back.If you go to the bottom of the game you'll see All Games.Click on it and look for the game you're look for and there you can trade it .Hope it helped.
I only see Battlefield, but the section is EMPTY. And there are so many videos for Battlefield Heroes on youtube
Battlefield will be a game we'll be expanding heavily too soon. The ad was posted in another section originally. All battlefield games go in the battlefield section for now. Thank you.
