Shooting people out of a slingshot is great fun and never seems to get old. Part of that might be due to all of the modes available to keep things interesting. The game comes with several single and multiplayer modes including a general High Score mode as well as Spank the Monkey, Mime Toss, and PAIN Bowling. There is also a free update that adds Fun with Explosives. All these modes also have several levels of difficulty that can be quite challenging to keep you interested as well.
