Edit user.ini in the deusex/system folder and change an empty key binding from (example!) 't=' to 't=talk' (do this for all occurances of 't='). In game, press T to make a line 'Say:' display at the bottom. Delete the word 'Say'. Always type on a blank line.

To activate cheatmode, type in "set DeusEx.JCDentonMale bCheatsEnabled True" without the quotes in the console. Now you may type any of the codes listed below:

Code Result

God Mode
invisible Invisibility
iamwarren Turn on EMP Field
allskillpoints Gives All Skill Points
allweapons Give All Weapons
allammo Refill Ammo
allaugs All Basic Augmentations
tantalus Kill Current Target
opensesame Unlock Targeted Door
legend Secret Menu
allhealth Full Health
allenergy Full Energy
allcredits 10000 Credits
allimages All Images
summon X Summon Item X (See List Below)
spawnmass Spawn a Mass of Enemies

Follow these steps to activate the Cheat Mode in Deus:

1. Go to the main option panel.
2. Position the mouse pointer onto the top left of the screen. 3. Press the Alt, Ctrl and C keys at the same time. The animation of the mouse pointer should stop at this point. 4. Use the numeric keypad to type in 3615, then hit Enter (also on the numeric keypad). 
While you are typing, you should see the numbers appearing on the top left of your screen. After you hit Enter, the animation of the mouse pointer should resume. You are now in Cheat Mode. 

Now, once you are in Cheat Mode, go to the normal, 3D game view. From here, you can press Ctrl-T to all the weapons and set all of your parameters to their respective maximums. This also gives you all of the objects of the scenario, although they will still 
appear in their normal locations - you will be carrying exact copies.

Important Note: Don’t press Ctrl-T while in one of the 2D panels or while you are swimming

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:
