CJ: Strike Back is a arcade styled game for Windows Phone where you play the role of the hero. A hero set on saving he city from invading aliens. Oddly, you do so by running up the screen jumping from side to side from building lining the sides of the screen, taking out the bad guys in mid jump. The further you progress up the buildings, the higher your score.
I'm not sure how much staying power CJ: Strike Back has but for short bits of time the game isn't a bad time waster.
