The Call of Duty: Black Ops “First Strike” Map Pack has been out on the Xbox 360 for a while, but it just hit the PS3 last week. To celebrate the release, Activision and Treyarch did something bizarre yet completely awesome. They took the Berlin Wall map from the Map Pack, put two characters on each side of the wall…and had them sing an epic power ballad to each other. We’re not kidding. It’s a power ballad as only Call of Duty could do with guns taking the place of guitars and epic explosions. Lots of epic explosions.
