Zombieland

Gone are the happy days, where you can relax with some of your friends.  The world already belongs to the zombies.  Furthermore, these zombies might be your friends since each time a zombie kills someone, it also turns into one of them.  Now, you are left alone, but you aren't ready to give up and is willing to fight for your life.   The idea here is to kill each zombie as fast as you can.  Grab the weapons that are hidden in boxes.  Try to kill as many zombies as you an. You have a default weapon, but is not as strong as the weapons that you will find in boxes.
