I meant to comment earlier but kind of forgot, despite being the first one to play (on stream) the pack...
The maps are all good, and some of them do a very cool halloween/haunted house theme. Night setting makes sense, though I found those maps to be just a bit too much on the dark side.
Some good use of AD tech.
ing: Good first? map with some proper weirdness/dimensional twists. All pretty cramped though, and at times oddly colorful lighting (however, one could argue it makes sense in that setting). I ran into a glitch where reloading a savegame caused the modelindex to be messed up so which had me fight invisible monsters. I didn't like that I had to hit the doors too open.
JCR: Nice graveyard setting; mandatory in such a map pack. Fairly dark, and I could imagine the bogeymen (if you pardon the pun) may have gotten to some unexpecting players. The end fight was a bit messy, but I managed to cheese the scrag queen when I was low on health.
Nyo: Another nice first? map, with a bit of exploration required. The corridors do look a bit samey, so I would have prefered if there at least had been a way to tell which areas/teleporters were completed. Bit overwhelming with so many monsters, but it seems the scrag mother had their health reduced?
Pinchy: Not really haunted house, but still felt well halloweenish with the rural-type of setting, a pumpkin farm. Nicely pulled off and I liked the openess of the map. I did have a serious problem with ammo towards the end, though. The pent secret teleporter is bad, because one seems to always fall down.
Qmaster: Great halloween setpiece, unfortunately a bit too dark again. For some reason it reminded me of some BL2 map. Unique puzzle approach. I derped a little there, unfortunately (shut up, otp!). Probably because there are two seperate task lists. Left the map with all zombies alive, and did I actually kill the minotaur or did it get away (can't remember)?!
xlarve: Not halloween theme at all, but I'm not complaining. It's a bonus map, typical xlarve style. Was fun, gg.
Newhouse: Cool start map, proper setting and introduction to the theme. I liked the pictures and the piano. Shame about the initial PIR. Had to replay from scratch a couple of times after hiccups in some maps, but never mind. Apparently AD changed the impulse 11 cheat.
(possibly not playing too well)
