Indeed, it's the perfect theme for Halloween. 

I had gray fog set in my map, but looking at the screenshot, red really does look better and suits the theme better. So when you get into jam3_tronyn, pull down the console and set "fog" to "0.13 0.4 0.0 0.0" (or at least that looks pretty close to the screenshot settings).

I am so looking forward to playing the rest of the maps. Congratulations to all the authors, and to OTP for organizing it! Great work guys it is seriously hard to believe that this has been one of the most content-intensive years for Q1SP ever! 

That was brutal! I played all of these on Nightmare and stremed the thing. It will be uploaded on my Youtube channel soon I hope.

Daz: I love the atmosphere here, it's proper zer. Cool layout overall, good use of monsters and nifty secrets (especially the useless one that's true to its name). The architecture is great for the most part, especially the central part. I especially liked the blood elevator. The ending is rather abrupt though. Good balance.

Ericw: Interesting take on zer, I like it a lot. It was properly brutal in some areas, especially the ending which could have had one or two health kits just before entering the final room. Architecture wasn't anything crazy but it did the job correctly and I liked the verticality.

Ionous: The most zer of the maps, I gotta say. Architecture was really gorgeous and really evil. Loved all these spikes and arches everywhere with the red windows. The main room with the blood basin was especially impressive. Gameplay is rather well balanced overall. It's a tad linear but other than that I think that one is one of my favs.

MFX: The king strikes back. While not as true to zer as, say, Daz's or Ionous', it is still properly evil and brutal. The rockwork is amazing, progression is cool and the secrets are, as usual, clever and rewarding (I especially liked the quick moves one). The skybox is insanely good especially, and all these floating rocks and moving parts were awesome. Lots of monsters to fight overall. Great woodwork and scaffoldings as well. I managed to "break" the map at one point but it's nothing too bad (just have to noclip a bit). My favorite of the pack.

Scar3crow: This is obviously a beginner's map but it was still funny and evil. I loved all the zombies, hacking through them with the chainsaw was properly satisfying. I especially liked the bloody vent that produced gibs after it was activated, hah! The map was visually plain and didn't really convey the zer feel but it's not too bad. The final arena on the other hand was a pain and not really fun, though I did like it when I panicked for obvious reasons.

Tronyn: Holy shit dude, how do you manage to create maps this huge so quickly? While having next to no zer vibe that was evil as fuck in its own way. The architecture and vistas are amazing! It really feels like a Doom map in terms of scale, it's quite something. While not as big as Something Wicked it's still goddamn big. The textures are very heterogenous but it works quite well. Good use of colored lighting as well, especially in some indoor areas, such as the libraries or the spiral staircase behind the gold key door. I liked the freedom you gave to players. The map was overall rather balanced with huge fights (seriously, all these zombies and grunts in the main area were really fun to kill), but the end fight is just way too hard. Had to godmode through it after several tries. In retrospect I should have left the quad and pent in the main arena alone, but oh well.

Overall, that was really really cool. Two hours of pure carnage in very hostile environments. 

I played your map with red fog and it definitely felt more sinister and evil than with the regular fog I got when I reloaded after quitting the game by accident. :p 

The fog is red on map start for me. 

since I already used it in ARWOP, Nyarlathotep, and the last map of Something Wicked; it's like it's my go-to evil move to make the atmosphere full of blood. But I could justify it in this map, since there's supposed to be rain and a moist atmosphere, pouring into a floor made of flesh, skull and bones, out of which the trees grow (thus the canals).

If the fog is red on map start that's great; it's probably because I only set the intensity, not the colour, in the map worldspawn, so it just uses the colour from previous maps/settings, as opposed to "neutral" (0 0 0 ) colour. Sweet! 

thanks for the feedback; I'm sorry about the ending. For future sufferers (lol at the whole crufixion idea in the Zer context), I included a secret in the end temple that could make it more doable. 

jam3_tronyn has a fog setting of "0.01" which seems to pick up the fog colour of the last map played (at least in fitz/qs).

Fun watching your stream, Skacky :) The pack looks awesome, I can't wait to play everything.

Also, I forgot to credit Quoth for the stars skybox my map uses, which I tweaked slightly to remove some jpeg artifacts.

Interesting, this is technically a bug in how fitzquake reads worldspawn fog ... 

From all of you!
But Tronyn, man i can�t believe this map is not bsp2. What a map!
Thanks to otp!
And thank you ericw for helping me out with that progs and all. 

Thanks skacky, yeah I skimped on visuals to get the entities close to done. Pretty much everything you see there, I learned to do right then and there. The Screw Cannon can be a bit terrible, but I was trying to avoid having any id weapons as far as I could help it.

The ceiling crusher was meant to keep the arena from being a continual circle strafe with in-fighting, however the whole rhythm got fouled up by monsters getting into the blood pool. Also, I had some messages not printing, which was frustrating to witness on the stream... Anyways, I wrote a post-mortem on the map and my mapping experience in general: http://scar3crow.com/2014/10/quake-map-jam-3-post-mortem/
