I did not make this tut all the credits go to "playinghalotoday" Spoiler Modding Single Player and Multiplayer modes in the Xbox 360 Xbox Live Arcade Game Zombie Apocalypse. TUTORIAL: 1. Stats for Zombie Apocalypse are stored in your Gamer Profile (Gamertag) file on your Xbox 360 Hard Drive / Memory Unit. 2. Search for "63E83FFF7A" in Hex and identify the result located directly below the achievement for "Friends in Low Places". The achievement can be identified by reading the text field adjacent to the hex field. HOW TO UNLOCK ALL DAYS FOR EVERY GAMETYPE (EXCEPT 7 DAYS IN HELL): 1. The byte representing the number of days unlocked can be found at 95 bytes past where the corresponding "63E83FFF7A" ends. 2. Replace your number of days with whatever number you want. If you want to have access to the last day, which is 55, you would replace the existing byte with "36" which represents 54 in decimal. The game will let you play on the last day. 3. If you go directly to day 55 in any gametype (Except 7 Days of Hell) and complete the level, you will get the "Anniversary of the Dead" 55G achievement. Anyone else in the game will also unlock this achievement. HOW TO UNLOCK ALL DAYS FOR 7 DAYS IN HELL GAMETYPE: 1. The byte representing the number of days unlocked can be found at 99 bytes past where the corresponding "63E83FFF7A" ends. 2. Replace your number of days with whatever number you want. If you want to have access to the last day, which is 7, you would replace the existing byte with "06" which represents 6 in decimal. The game will let you play on the last day. 3. If you go directly to day 7 in the 7 Days of Hell gametype and complete the level, you will get the "Hotter Than Hell" 25G achievement. Anyone else in the game will also unlock this achievement. HOW TO UNLOCK ALL GAMETYPES: 1. The byte representing the number of days unlocked can be found at 111 bytes past where the corresponding "63E83FFF7A" ends. 2. Replace the existing value in that byte with "FF" to unlock every gametype. 3. To change your weapons in the "All Weapons" gametype, press left or right on the D-pad to scroll through your available weapons. TIP(S): 1. A byte is represented by a set of two evenly spaced hex decimals. For example: "00 FF 33 22", would be 4 bytes. :thumbsup:
