This game is more strategy and puzzle related than it is about sniper skills. The object is to rescue civilians from hostiles that are holding them captive in each level and snipe all the baddies in each level. In some cases you will have to throw rocks to distract the guard and then snipe him so that he does not cause harm to the civilian. In other cases you will have to use explosions and physics to your advantage to collapse entire structures on top of the baddies. This is why the game is more puzzle based.. because all the shots you take require very little skill.. it's all about making the right shots at the right time.
