Activision's latest shooter, Call of Duty: Black Ops, only went on sale at midnight yesterday but gamers have already combed over the new release and discovered a wealth of secrets and Easter eggs.
Once you've gone through the main story campaign and sunk hours into the slew of multiplayer and zombie modes, there's still more to play with the secretive Dead Ops Arcade mode. The hidden mini-game is an arcade-style shooter, filled with zombies, that's reminiscent of arcade classics like Smash TV.
Activision has been trying, fruitlessly, to keep videos of the secrets off of the web, and the publisher has ordered YouTube to take down any videos of the hidden mode. But you can find out exactly how to find it, right here.
Here's what you'll need to do: The main menu screen for Black Ops has you strapped by the wrists to a Cold War <a href="/news/archive/2009-04/23/'sleep-research-twisted-to-justify-torture'"
title="Sleep scientists: Research twisted to justify torture">interrogation</a> chair, in front of a wall of monitors. However, by repeatedly pulling on the left and right controller triggers, alternately and as quickly as possible, you can break free from your shackles and explore the room.
Over in the corner is an computer terminal, which you can interact with. Once you're in, a pop-up keyboard appears where you can enter different commands. Type in "DOA" and you'll get access to the Dead Ops game. If you want to play it again, it will be available under "<a href="/news/archive/2010-09/16/igfest-bristol-gaming-festival" title="Zombies invade Bristol for Igfest">Zombies</a>" from the main menu in the future.
You can also play cult classic 70s text adventure Zork by typing in, you guessed it, "Zork".
That's right, you can ignore your newly purchased, high definition, 3D, online shooter in favour of a text-only, interactive fiction game featuring the iconic line, "You are likely to be eaten by a grue." You can also type "help" for more commands, letting you read extra backstory, see concept art and listen to the game's soundtrack.
Call of Duty: Black Ops is available now on Xbox 360, PlayStation 3 and PC.
