Welcome to Gaia! ::

I need a little help collecting all the keys you have to find after quadraxis

Ah, there's somthing I can help with! mrgreen
Ok, if you've been to the place in the dark world that looks like the Hall of Honored Dead in the light world, then all you had to do was scan the pilars near the body of the Luminoth warrior and they'll give you the positions of the bodies of other Luminoth.
After you have all of A-Kul's Clues, go looking for the bodies and scan them, if you haven't already.
If you have, just return to the spot where the bodies are, but in the Dark Realm. switch to your Dark Visor and you should see a Floating Ing Cache.
kill it to claim your key.
Oh, and the one key I can remember the location of is where your ship crashed, but in the dark realm.
Hint: If you use your Dark Visor in certain places, like where your ship crashed for instance, you will see an outline of the Floating Cache. Just get to that particular room in the dark world and kill the cache, and anything else that gets in your way.

EDIT: also, use the log book scans you get from the Luminoth warriors to help you figure out where in the dark world you need to go, if you get lost.

I'm not sure if this is the same fight that you're talking about since i don't own MP1 or played it at all. I just searched up a video on it and it just shows that you have to hit it's legs and arms first. then he changes into phase 2 and different space pirates comes out. You kill those (don't have to) then switch to X ray visor and hit the Omega Pirate when it's vulnerable. Then he just goes back to Phase 1 not too hard. I hope that helped you wink

Next time try to scan the creature it gives tips on how to beat it.
