A good techbase map! I really like the overall architecture such as the big pit with chalk full of monsters of varying heights and the spectre arena fight. Its also includes a lot of fun gimmicks, very impresive for 96' (crushers, invisible walls, multiple buttons that activate platforms and the likes). I enjoyed playing through this map...especially during that spectre arena fight, I had fun with that part. Maybe one improvement would be to include more proper textures in order to fit the overall feel of the map and maybe some slights improvements on the architecture and maybe more monsters is needed because of the high ammo placed all over the map but overall, I enjoyed it! :)
Another one of the early maps from Wraith, is a nice "Techbase" style map but unluckily have unaligned sector textures and a weird mix of metal and lava without too much lava, but this mix actually works. Monsters are used in a clever way, I liked the puzzle too, even if it's easy to break if you understand the trickery.
Overall, nice map, it's playable only on zdoom-compatible ports.
