File Edit Cheats
The following cheats involve editing a game file, which can potentially crash the game or make it unplayable if you mess up. Always make a backup of the original file before proceeding, if anything goes wrong you can simply replace the file with the backup.
Unlimited Resources Cheat
Use a text editor to edit the "proto.xml" file in the "data" directory of the game folder. You may first need to uncheck the "Read Only" attribute of that file's properties in Windows Explorer, right click the file for that option.
Search for the text "CrateOf". You will find CrateofFood, CrateofCoin, CrateofWood, CrateofFoodLarge, CrafteofCoinLarge, and CrateofWoodLarge. For all these entries, find the tag "InitialResourceCount" and change the count to whatever desired.
For example, the normal crates each have "100.000" of the resources. You can change the "100" to "99999.000", etc.
Unlimited Unlock Points Cheat
Open the sp_yourcityname_homecity.xml file located in \My Documents\My Games\Age of Empires 3\Savegame (dont forget to make a backup of this file) find this line <skillpoints>.
The line should look like this <skillpoints>xx</skillpoints>, where x is the number of skillpoints you currently have. Change the xx to a high number such as 999, save the file and start Age of Empires 3.
Go into a skirmish game, go to manage your city and you will now have 999 unlock points to unlock various things for your city.
Increase Card / Deck Unlock Points
Go to My Documents\My Games\Age of Empires 3\Savegame open the sp_yourcityname_homecity.xml (make sure you back up this file) and find the line <numpropunlocksearned>.
The line should look something like this <numpropunlocksearned>xx</numpropunlocksearned>, where xx is the current number of card unlock ponts you have. Change xx to a high number such as 999, save the file, start Age of Empires 3 and go into a skirmish. Go to where you manage your decks and now you will have 999 unlock points to get more cards for your deck.
Invincible Units Cheat
In the game folder, open the folder called data. Right click proto.xml and open with notepad. Press CTRL and F. Type in the name of the unit you want to find, e.g.: Explorer. Scroll down until you see all kinds of things starting with <Flag>.
Anywhere in that area, make a new column and press CTRL and TAB twice. Type:
and on another line type:
Save the file then open AOE 3. Send your explorer into battle. He Will Never Die!
