Nothing to say ...
did you use q3 textures ??? (just see the screenshots) 

Yes it was dark, I played at gamma 140, a new record for me, with the lights off. Very beautiful, in a Quakey way. Nothing wrong with a little light, ya'know ;) ...

I thought the mini-fiends were fine except for the dark (bad skins, what skins?), fortunately easier to kill. If anything I had more problem with the overpowered monsters but then I played a bunch of Unreal before it so ... Anyway I liked the positron, no problems at all running the level despite instability on everything else and crashing to 16 color hell a couple days later. 

I've just started playing through the pak and I like it so far! Although the fiend queen was strange to kill.

At first I emptied all my ammo and still just couldn't kill her. After restarting my last saved game, I moved closer and took her down with just a few DBS shots right in the face. Weird ...

However, I noticed one bug that you might want to fix; it's the model freezem.mdl that needs one more skin (it only has one now and there's a reference in the progs.dat (in weapons/freeze.qc) for a second one).

In FitzQuake you'll get error messages printed all over the console when you fire the freezer gun, other engines might behave in another manner.

I just duplicated the first skin and then it was OK. I had the same problem several times when fixing up "The Source of Power" so I knew right away how to pinpoint it. 

she has a force filed around her which lowers when you get up close within her melee range. 

The Queen Demon is invulnerable unless she attacks.

So, you get into attack range, hit her when she tries to hit you, back off, lather-rinse-repeat.
