Contract Killer is a first-person sniping game in which the assassin takes on secret missions for a variety of clients. The mission is set in a realistic 3D environment with the assassin having a choice of a variety of weapons to accomplish his mission.
Each mission costs a certain amount of energy. Energy restores over time, but you can also purchase snacks with Microsoft Points. As with Gun Bros and Bug Village, the in app purchases are optional and the mission can be accomplished, albeit at a slower pace, without paying a cent.
Contract Killer will hit the Marketplace on Wednesday, July 18. Like Gun Bros, itís free and includes 200 GamerScore worth of Achievements.
