If you enjoyed the arcade classic Missile Command, you will be happy to know that today's time waster is right up your alley. M.A.D., short for Mutually Assured Destruction, takes the classic Missile Command concept and builds on it with a variety of different upgrades, abilities, and enemy projectiles.

The goal of the game is to survive an onslaught of incoming missiles. You do this by shooting your own missiles at the incoming ones, which requires a little bit of reaction speed and dexterity as you have to aim yours on an intercepting path. However, although you will initially only be bombarded with plain go-in-a-straight-line missiles, you will soon have to face homing missiles and missiles with irregular flight patterns. Of course, to deal with these oddballs, you have an arsenal of support weapons to help make things easier, ranging from flak weaponry, emp discharges, and localized time distortion fields.

What all of this really means, is that if you have some time that needs disposing, M.A.D. is there to help - especially if you enjoy time wasters of the survival type.
