Crunch Time 
Armed with nothing more than a staple gun, it's your job to battle through three levels of an office building jam-packed with zombies and exploding fire-extinguishers. Do you have what it takes to battle the 3pm crunch? If so, you'll love this game:

You know that feeling when you return from the restroom and all your co-workers' brains have exploded, and they have been transformed into blood-thirsty zombies, infected by an intergalactic computer virus disguised as check-this-out mail attachment? This is it.

So go on, vanquish the zombies in Crunch Time.
