Kill your neighbor from the comfort of your iPhone or iPod touch! gpsAssassins is a location-based game of kill or be killed. As an Assassin, you earn Blood Money and advance your Rank by attacking players who come within range. Becoming a Death Dealer is not easy: Opponents can Hide, wear Armor, and launch devastating Counter Attacks! Spend Blood Money to stock up on better Weapons and Armor. Scan for targets as you move about. Attack with short-range weapons to take out those who get too close and long-range weapons for those others within reach. Distinguish yourself with Custom Weapons and Armor. Rise to the top and devastate your neighbors in a battle for dominance.
