Retailer GameStop is currently offering a pretty solid deal on two of Activision's big FPS games.
Until December 27th, when you buy Overwatch or Call of Duty: Infinite Warfare, you'll get a copy of the other game for free. This is good for the PlayStation 4 and Xbox One versions of either game.
For Infinite Warfare, it appears this deal does not apply to the game's Legacy Edition that comes with the Call of Duty 4 remaster. Go to GameStop's website to get started shopping.
Infinite Warfare failed to meet GameStop's sales expectations. The game did not stay at its $60 price for very long, as it's now available for $40 at GameStop and other retailers. The Legacy Edition is also down $20, available for $60 at retailers across the country and online.
