The iOS games studio Mobigame - best known for titles like Edge and Perfect Cell - has teamed up with Amnesty International to publish a game raising money for the human rights advocacy organization, observing its 50th anniversary this year.

Bulletproof, costing 99 cents on the iTunes App Store, places the player as a political prisoner in front of a vaguely North Korean firing squad. The gameplay objective is to deflect incoming shots by touching on green crosshairs indicating their target. The frequency and difficulty of the volleys increases with each round.

Mobigame and Amnesty International say the app is meant to raise awareness of Amnesty International's mission and, of course, proceeds from its sale contribute to that.
