Get a pak editor and go into your assets0.pak, it should be in your 'ext_data' folder under the name of npcs.cfg. Extract that and open it up with any old text editor. When your done put it a new pak3 under in a folder named 'ext_data' with the name of npcs.cfg.
Simply delete the new pak to return to your old npc's.
You should see aim, reaction, agression, ect. under every npc.
