* The lighting seemed random, and hurt my eyes.
* The textures in the tech areas made little sense.
* The map is WAY too crowded (300+ monsters on a rather small SP map)
* The ogoro trap at the end was ruined, because you could see their arms through the walls.
* Making the player go through again and again untill all the monsters are killed is a cheap trick.
* There were too many map models, making the crowded issue much worse.
* Several areas were too dark to see (making navigation through such small and twisted tunnels nearly impossible)
Overall, it deserves a 2 because there is at least some thought put into it, and there are few apparent bugs.
