I found this on:

The author says:
Hey guys, here is my BASIC Editor for Deus Ex.
NOTE: I don't actually know if the "Level" is level (the number was right before the amount of Experience. Or what the max Level is (I left the max you can put in to 2.1 billion, use wisely).
To use just extract your Savegame.sav from your Deus Ex Human Rev save.
Thanks to "eLif" from 360haven.com for supplying the saves. The Editor takes 5-10 seconds to load the save after you load it, so be patient.
You have to register to thetechgame to download it.
