I forgot to include this fixed version of allcap's map. It's not 100% necessary, but it does fix a secret, a potential soft lock and tweaks to lighting.

I've updated the pack there. The Quaddicted link is now the older version since we cannot replace files here. Use the Archive.org link please

I updated the OP with notes about which link points to the latest version and which one doesn't. If you like I can remove the Quaketastic link entirely.

I'll make some quick reviews:

- Who let the fiends out? : Okay, this map has one secret that I can't find at all. I know there's a secret message (with a super easy trick to go straight to the ending), but that's not a secret.

Oh, and I noticed there was an easy way to NOT teleport if you fall down... And softlock yourself (same for the fiends that jump far away). Otherwise, a quite nice looking map. Loved it.

- We all float down here : I liked the design of the may, but I've noticed that the elevators mid-level followed by the slope jump right after it are really painful to make... I died countless times because Ranger wasn't able to move to the ledge.

- Floating Waste Processing : WOW, WHAT A MAP! Not only it's huge, but it was really fun to play (even if, due to gravity ((?)) many lifts made me lose armor/life). Killing those zombies far away was probably the highlight of the map. I missed one secret though.

- Somnus : very simple map, I enjoyed it.

- The Bouncy Place : Okay, the beginning of the map heavily puzzled me. Did I have to make a rocket jump using a vore to progress? I seriously didn't understand the proper way to do it, so I had to get creative. Otherwise a map full of deadly battles due to the small size of the map.

- Untitled : mixing water with low-gravity was really creative. Also, using only the LG scared me in a lot of places during my very first playthrough (killed myself accidentally right after the silver door hehe!). Definitely one of my favorites.

- Pyramid Scheme : That was a nightmare to find the very first secret. Also to jump properly without falling. Despite its simplistic looks, it was one of the hardest maps I've ever played.

- Suilebis : That was a nice little slaughter map (if I can say it that way). The final battle with shamblers was a nice reward after all the pain you had slightly earlier :P

- It's time to leave my prison! : I don't know why, but jumping maps suited the theme well. It's extremely small and short, but it was enjoyable while it lasted.

- Eternal Fall: a map that took me a long time to complete it due to the chaotic beginning and ending. I wasn't able to find many secrets (although I missed 2 on purpose, and missed a few monsters because I lacked some RL ammo at the very end. Oh well. At least I was able to free my frustration there :P 

Yes, you use the vores to jump out. That's why the pentagram is there. 

Thank you. Yes, it would help if the Quaketastic link was nuked when you have a second.
