Destroy All Humans!, a nice game which will keep you entertained if it's blowing up houses or obliterating humans. All the probes to find in the different level will leave you playing it for hours as there are so many to find. I am 97% through the game and have about 5 more probes left to find. I CAN'T FIND THEM ANYWHERE!!! But I am sure I will.
It is a good game and I don't think that you will be wasting your money.

Ma.. Mama.. Martians!!!!!
The themes of Grand Theft Auto and the humor of The Simpson's, this makes Destroy all Humans everything else, and its own at the same time.
You play as an alien Martian, of the race called the Furons, and the only reason you exist is to... Destroy all Humans. One of your predecessors has been captured, and you have been promoted to bring him back. Your journey brings you to a backwater planet known as earth. Classic oldie martian technology, such as the Death-ray and the Anal probe, are included, bringing out the most funny game I have ever played. The boring side missions slow down the game, and the fact you have to pay for your own upgrades in DNA, which is time consuming, and gets kind of reoccurring. The cities don't vary as much as they could have, but an excellent storyline! The funniest thing, is that the mayor from of one of the cities, sounds just like Mayor Quimby. lol. I still cant get over it.

I bought Destroy All Humans! about a week ago, best way I can describle this game, is the film "Mars Attacks", but you play as the aliens.

Very funny game to play, but gets a little too samey.
