Find and open "defuser.ini" in your BioShock installation folder. Find the key you want to bind the code to and set the bind (for example, "F10=god").

Save the file and start the game, while in game press the bound key to toggle.

Note: The cheat can be deactivated if a video cutscene appears or if you move to a new area.

Follow these instructions to be able to obtain any or all of the following tonics / plasmids.

1.) Make a text file, call it Plasmid.txt

2.) In the file DefUser.ini, which is located inside the Release folder, set up a key with the following command:

exec Plasmid.txt

3.) Edit the text file you have just made with any of the following commands and place it into your BioShock "Release" folder.

4.) Once you are in the game, hit the button you had bound to "exec Plasmid.txt"

5.) Head to a gene bank.

6.) Enjoy your newfound powers!

Create a text file named Weapons.txt with a text editor and place it in the "System" folder in the game directory, which is typically "C:\Program Files\2K Games\BioShock\Content\System". In the "User.ini" file used in the "Cheat mode" section, bind the following command to any key exec Weapons.txt Edit the Weapons.txt file you have just made with any of the following commands listed below. Once you are in the game, use the key you have bound to the "exec Weapons.txt" line. Alternately, you can use Plasmid.txt file if already created and use the same key for both types of cheats. Spawned weapons and ammunition will appear directly in your inventory. Note: The game has default maximum ammunition carrying capacities for each weapon (for example, you can normally carry a maximum of 48 standard pistol rounds) Thus if you try to summon 999 pistol rounds with the pistol in your inventory, the game will automatically limit you to 48 rounds. However if you summon 999 rounds before you first acquire the pistol, then you will have 999 rounds available in your inventory.

Note: v1.1 of the game is required to enable all codes. Some, but not all, codes can be used with earlier versions. This procedure involves editing a game file; create a backup copy of the files before proceeding. You will need to allow hidden files and folders to be shown in order to edit this particular .ini file. Use a text editor to edit the "User.ini" file found in the following locations: Windows XP: C:\Documents and Settings\<username>\Application Data\Bioshock\ Windows Vista: C:\Users\<username>\AppData\Roaming\Bioshock\ Set a key binding in the User.ini file to any of the following codes (for example, "F10=fly"). Then, press the corresponding key during game play to activate the corresponding cheat function. Note: Any active codes are disabled when a new area loads or intermission sequence plays. General codes are as follows:

1. Create "upgrades.txt" in \Content\System within your BioShock installation folder (i.e. C:\Program Files\2K Games\BioShock\Content\System). Add any of the codes listed below to upgrades.txt and save it. Be sure to preserve the spacing. Each code must be on its own line in the file. 2. Open “User.ini” in “X:\Documents and Settings\[username]\Application Data\Bioshock” for XP or “X:\Users\[username]\AppData\Roaming\BioShock” for Vista. You may need to enable viewing of hidden files and folders to find it. 3. Find the section entitled [Default]. 4. Within this section, find an unbound key that you want to use and bind it to the command "Exec upgrades.txt" (i.e. F7=Exec upgrades.txt). NOTE: If you give upgrades for a weapon you don't have yet, the upgrades will be applied when you pick up that weapon, so you don't have to wait to get a weapon before you upgrade it.

1. Create "research.txt" in \Content\System within your BioShock installation folder (i.e. C:\Program Files\2K Games\BioShock\Content\System). Add any of the codes listed below to research.txt and save it. Be sure to preserve the spacing. Each code must be on its own line in the file. 2. Open “User.ini” in “X:\Documents and Settings\[username]\Application Data\Bioshock” for XP or “X:\Users\[username]\AppData\Roaming\BioShock” for Vista. You may need to enable viewing of hidden files and folders to find it. 3. Find the section entitled [Default]. 4. Within this section, find an unbound key that you want to use and bind it to the command "Exec research.txt" (i.e. F7=Exec research.txt).
