Update: As some commenters have pointed out, it looks like the deals are no longer available. We hope you managed to snag one.
We bet you were really hoping to not spend an extra five dollars today. We're sure you thought to yourself that you've got plenty of games to play and, honestly, what could you buy with five bucks anyway? The answer: Worms 2: Armageddon on Xbox Live Arcade. The good people at CheapCollegeGamers have uncovered a pair of great deals on Amazon. First and foremost, Worms 2 is available for a paltry $5, fifty percent off the usual $10 price tag. If you don't have it already, it would be crazy not to buy it at that price.
Amazon is also offering Puzzle Quest: Galactrix at a discounted price of $10, half of the normal $20 cost. Granted, it's not quite as easy to recommend Galactrix as Worms 2, but $10 is a much more palatable price. Now go buy Worms 2.
