Deus Ex console commands

Press the chat button and delete "say" so there's only ">" left.

If you have a older version (anything less than 1.112fm which is listed in the main menu) skip the below section.

Type the following... Set DeusEx.JCDentonMale bCheatsEnabled True.

Now press enter, nothing will appear, but you have just activated cheats. Because you will need to redo this for every level, you can open up 'user.ini' and add 'bCheatsEnabled True' in the [DeusEx.DeusExGameInfo] section of the file to allow cheats to be activated forever.

Enabling Cheats - Method Two

To activate cheat codes add -hax0r to the shortcut or command line of the icon for the game, ( 0 is a zero not an o as in ok ). Then Edit user.ini in the deusex/system folder and change "Tilde=" to "Tilde=type" ( do this for all occurrences of "Tilde=" ). In game, press ~ then type any of the cheat codes listed below:

Older Versions
If you have the latest patch you shouldn't need to edit any files, with the latest patch, the button "T" is default set to "Talk". If you have messed with the keyboard configuration or that you don't have the latest patch, you will need to edit a file. The file is called "user.ini" and it is in your system folder of your deusex root folder (so for example C:DeusExSystem). Open this in any Text editor, notepad is best. Once opened, search for "T=", this should be in a section called "[Engine.Input]". Once found, you need to edit its value to "Talk", to do this, after the =, type "Talk'", so it should now look like this:

T=Talk

Now go into the game, press the 'T' button. You will see the following at the bottom left of the screen:

>Say

You will need to press backspace till you remove the 'Say', so its just ">" now. Now you will need to type what is written at the top of this article.

Cheat List
You can bind any of the following cheats in the "user.ini". For example changing the value "L=" to "L=god" will give you god mode in game by pressing that key.

When using the "Summon" and "Spawnmass" cheats, here are the names of the actual items you can spawn. So for example: if you wanted ten 30.06 boxes, you'd type in "spawnmass Ammo3006 10", without the quotes.

Ending C: Follow Tracer Tong's advice and destroy the world's communications.

Bring items back to the first mission
Start a new game in the middle of a mission, any items which you were carrying will be with you at the beginning.

Free Items
Make sure your inventory is full before attempting this. Go up to anyone who will sell you items and make a purchase. Look down at your feet. The item you tried to purchase will be down there. This can also be done for items given to you like the upgrading canisters from Jaime. This trick can be done as many times as you like as long as your inventory is full.

Free skill points
Before talking to Gary Savage on the rooftop at the sub base (save name New West Coast - Sub Base), make sure your inventory is filled up. Then talk to him. He will offer you a augmentation canister, and you can't take it. You will get 500 skill points. Keep on talkin' to him, and the skill points just keep rolling...

Bypassing Laser Beams
Simply walk close to beam(s), do a quicksave and while saving hold down Up Arrow. When the save is complete, you should be on the other side of the beam(s) without triggering any alarms.

Instant Lockpicking
Find a locked door, then use a lockpick on it. As you start to pick the lock, go into any of the menu or subscreens. After 10–20 seconds (it depends on the lock and your skill level), leave the menu and return to the game. You will have instantly picked the lock using a single pick, even if it required more than one! This trick will also work with Multitools on cameras, alarms, etc.

Unlimited Inventory Space
Once you run out of inventory space, click and drag away a large item from the inventory then press I to click off the screen. The next item you collect will appear under the large item you dragged off.

Infinite crate items
Take any supply into a loading screen. Whichever item was inside the crate will be duplicated and fall into the new map. This can be done infinitely so long as the crate is not broken.

Secrets
Liberty Island Secret Locations
 * 1) 1-Opposite Harley Filbenn's office at the north docks is an explosive barrel. Push it into the water and blow it with your pistol. You also have the option of trying to manually unlock the hatch. Jump into the water and search the sunken speedboat for some extra items and weapons.
 * 2) 2-In Alex Jacobson's office, just opposite the storage closet, near the wall, there is two secret tiles that will lead you to a secret storage space. Different items will appear all the time so be sure to check back regularly.
