User summary: Characters in Air Patrol are assumed to be heroic crime-fighting adventurers who use future tech, though the game is set in the past - yielding something of a steampunk feel. Characters have Skills and special abilities. Additionally, the game uses a "Risk Dice" mechanic that lets characters expend a limited pool of dice to increase their success odds, but at the possible cost of adding complications. Note that two versions are available for download; both are functionally identical.
