From Glu Mobile:
They might call you an enforcer, or an assassin. Call it what you like - you're a contract killer. Pulled into a world of bounty hunters, mobsters and criminals, you must check in with your contacts and accept secret missions that only you can handle. Select your weapon of choice from an inventory of sniper rifles, assault rifles and machine guns. Locate your target, zoom in, take aim and go for the headshot to earn cold hard cash. You might eliminate a crime boss and escape without being spotted, or you might walk straight into an ambush.
