Stealth Search for Doomgiver
Hi people, I need help again.
So far I have been noclipping around jump puzzles and this part I am truly stuck.
I am in this map where I had to search for Doomgiver in stealth mode... or at least not detected. Which means god mode isn't gonna help. That is not really a problem. I managed to get into the ventilation tunnel and go to the other side, past the electrified pull (of generators?), where the alarm is faulty, and killing the Imps are possible. But then I'm stuck.
There is one door requiring security key, which I can't find. Can't find any Imp officer to kill to get that key. Another door with red light on (locked). That's about it.
I noclip around to the top of those walls, but can't be sure what I can (and need to) do next.
Looks like I'm missing something again. Also, it seems that once I get past that electrified pool (with cone-like shapes of generators?), I can't seem to find the way back. I noticed at the other side of one of the walls is another black, electrified, field of some sort. That one has an alarm button right next to it, though.
Ok, back to where I am stuck... any hints? Any walkthroughs?
