Played on normal and nightmare difficulties.

Quite good. you can see the base as a speedmap and the parts inspired by Quake 3. Provides good and fun combats here and there, being the best the ones near the first gold key's door, but some not so good but never bad placements, like the ones at the first ''room''. The layout is simple but very well built and connected. The brushwork is a bit plain but effective, and makes up for its plainness with the usage of textures and lighting. It has some places to look at where to get there ... which is good. Ammo isn't well distributed at the beginning and the amount is over what you can carry even if you backtrack, but nothing outrageous. Health and armor are well used. The secrets were nice, with the first as my favorite, simple and relies on exploration. I don't like the second but the third is one is one that i like, even while considering that the way to get to it isn't to my tastes, even though it is well executed. They are all are well placed and with the right reward inside. Difficulty is a bit over ID maps, and there is no unfair parts.

To summarize. 4+
