- In the Data Vault, highlight the "S" logo that would typically allow you to access Dead Ops Arcade 2. Press and hold all four shoulder buttons on your controller. As you continue to hold those buttons, press X+Y on your controller (or the equivalent) and you'll bring up a secret menu, where you can enter cheat codes. Enter one of the codes below for the corresponding effect.
MANIFEST - Receive up to 100 Fabrication Kits
DREAMLAND - Access Nightmare Mode without first clearing the campaign
- Easy Shortcut to Round 15 - Once you spawn in Shadows of Evil, look up to the Shadow Man and start shooting him. Continue to do so without giving it a break and you'll eventually survive the round, then advance to Round 5 with 1000 points. You can buy the RK5, then continue shooting the Shadow Man to quickly advance to Round 10 while obtaining another 4000 points. Keep shooting him from there, and soon you'll advance to Round 15 and gain 11,000 points. At that point, the Shadow Man will disappear. You essentially have skipped directly to Round 15 and have 16,000 points to show for it.
