Does Everyone Have 'Dead Ops'?

I was just wondering if everyone had the Dead Ops zombie map. Its free on your disc but you have to access it from the main menu screen. If you do not have it here are the step to get it.

1. From the main menu where it lists Campaign, Multiplayer, Zombies tap R2 and L2 alternately rapidly. Mason will break free of the restraints and stand up out of the chair.

2. Walk around the room and find the computer. Press square to access it. Type in 3ARC UNLOCK. Make sure there is a space in the middle. After you hit enter a message should appear on the monitor saying cheat unlocked or something of the sorts.

3. Enjoy a different take on zombies, very arcade style, overhead view, zombie killing game.

there are more things to do on that pc dude. Type ZORK to play the first game (textbased) ever. Made by a company purchased by Activision later on. You can also press DOA for the dead op arcade. If you press 3ARC intel, you have found all intel BEWARE!!!!! if you use the cheat to have all intel, you wont get the throphy on ps3 so DONT USE IT!!

Yes dont do the intel one, and yes i know there are many more things to do on the pc but i was just making sure everyone got the free arcade game that comes on the disk
