I would stay away from that mod. Seems to add/change game mechanics which have never really been in Deus Ex.
Honestly, I found the story to be a bit long-winded. By about 4/6s or 5/6s onwards, I just wanted it to be over. Of course, I went for the most complete ending I could go for.
EDIT: just remember that the key to every Deus Ex is hacking. Always max that out ASAP.
