A stealth-based action-adventure game where you play as a ninja assassin. You have to kill the guard and get the keys to the next level. The game starts out with you sneaking into the building. Once you're in the room, you have to move quickly and silently. Avoid the lasers, cameras, and other obstacles so that the guard won't see you. Collect the keys and money, and then head towards the gate. Once you get there, you can open the door and go to the next level.

To avoid getting caught, use the navigation bar to guide your path. You can use any object to kill the guard, such as a computer, printer, or any hard object.
