What lies beneath titan-426

Lengthy, pretty, and fun map - five stars. The visuals are great, using a unique texture set with a mixed gothic/hellish/tech style (also reminds me of Plutonia brickwork). The architecture & detailing are quite appealing and also very consistent throughout (and don't interfere with movement like some 00's maps). It requires ZDoom, but you wouldn't guess it from the level design - it's all quite standard stuff besides the particle effects on teleporters. I notice a comment complaining about stealth monsters, but i dont remember seeing any such thing. The only custom monster is a reskinned SS Nazi, and they're quite rare anyways. All monsters do have new sound effects though, from PS1 Doom. There's over 500 enemies, but it never feels like a grind or a slog because you get plenty of powerful weapons & ammo for them. And the enemies are spread out over a fairly long level (the tally screen told me 40 minutes, but it's probably double that including time lost due to death). The level design is good, although some areas are a bit overly symmetrical. There are multiple times when enemies mass spawn in, but you're given a preview of who will spawn and where, so you can plan ahead, which is interesting. Overall the difficulty is medium and reasonably balanced, although there was one trap near the very end I felt was unfair (trial & error style) - you'll probably figure out what if you play it.
