This is basically a better version of Costa’s freeride mod.

Download.

1. Extract preorder_hack.zip to your game directory. It should not overwrite any files.
2. Set PreferLocalFiles in Engine.ini to 1. This file can be found on Vista/Win7 in C:\Users\Username\AppData\Roaming\Ubisoft\Anno1404\Config\Engine.ini. It’s probably something like C:\Documents and Settings\Username\Application Data\Ubisoft\Anno1404\Config\Engine.ini on XP.
3. Start any game, rename one of your ships to the The Silver Ship. If you are playing the game in a different locale than English, you will need to extract change_achievement_name.zip to your game directory as well.
4. You should see at least one achievement unlock.
5. Silver Ship and Preorder Emblem should now be enabled. Silver Ship toggle is in game options, Preorder Emblem is listed with all other unlocked emblems.
6. Remove the extract file(s) after you’ve saved and exited the game.

My favorite being prototypef.exe Level=manhattanTest which starts the game in a game with all upgrades unlocked, no missions, and no infected & military.
