Ultimate Assassin is the third installment of the top-down stealth game. There are several missions, divided into different difficulty levels. In each mission, you will have to stay out of the guards' field of vision and kill the target. Once the target has been killed, a blinking spot will appear on the map, which you must reach to complete the mission. You have two abilities that will help you complete missions; speed and invisibility. Your ability bar at the bottom of the screen limits how long you can use these abilities.
