The newest addition to Kabam and Marvel's Contest of Champions mobile fighting game is actually a second variant. While Deadpool was already in the game, now his brutal X-Force grey and black costume variant comes in as a playable character.
The character, available now, also recently came to Marvel Puzzle Quest as a playable character, though there his special abilities vary from costume to costume. In this game, it's just a variant in the colors of the costume.
