发一个黑色行动里面的小电脑CHEATS：Cheat: Codes
On the Main Menu, alternately tap RIGHT and LEFT triggers (or hold the Space bar on a keyboard). After a bit, youll stand up. Leave your seat and examine the back wall. A small black and white computer terminal can be found here. Approach it and enter these codes using the on-screen keyboard in the "Central Intelligence Agency Data System." （稍微翻译一下，这个大概谁都懂，游戏机平台的拼命摁LT RT，PC平台摁住SPACE键，MASON就站起来了，到后面的黑白终端电脑里输入下面的密码）
DOA - Play the super-awesome top-down Smash TV-style Dead Ops Arcade minigame（街机迷你电视游戏···死亡行动）
3ARC INTEL - Unlocks all the intel in the game for viewing (Disables Closer Analysis Trophy/Achievement) （解锁所有INTEL，注意：他会使你无法解开相应的成就）
3ARC UNLOCK - Unlocks all levels and Zombie Mode levels（解开所有等级和僵尸模式等级）
ZORK - Unlocks Zork I: The Great Underground Empire (an incredibly great text adventure from 1980) which you can play on the console (!) （伟大的地下王国，一个1980的难以置信的文本冒险）
HELLO SAILOR - Unlocks Zork I: The Great Underground Empire (an incredibly great text adventure from 1980) which you can play on the console (!) （这个有些奇怪，跟上面的一样···）
HELP - Gives you a list of commands to interface with the console -- you can check mail messages and perform other mundane functions, some of which are listed below（列出所有命令集）
DIR - Gives a list of audio files and pictures which you can open with the CAT command (eg CAT NoteX.txt)
WHO - Gives a list of login names for use with the RLOGIN function (but they require a password)
RLOGIN - Log in with username and password (full list of logins below)
FOOBAR - Gives a strange message ("Fee Fie Foe Foo!")
ALICIA - Loads "Alicia," a virtual therapist
（灰色的是大家也许不感兴趣的，所以也不再介绍····）
最后给出一个连接，里面介绍了越南下山踢油桶的关卡攻略，终端的人名（有些有密码，有些则没有），一个关于在第5张僵尸图换音乐的复活蛋。
