An extremely challenging mod which forces players to think outside of the box... in order to get out of the box. Each room is a unique puzzle, and is always full of surprises. Not for players who aren't up for an intense, claustrophobic experience.
I had no idea what to expect when I downloaded this mod. I'd like to say that I was pleasantly surprised.
PROS
1. This mod is rock solid. I didn't encounter a single glitch while playing.
2. This mod is challenging. Many mods claim to be difficult or challenging, but this mod really delivers. I had to extensively examine my surroundings to finish each stage.
3. This mod has good maps. Overall, they look nice.
4. The ending makes you feel like a badass.
CONS
1. The design of some models and brushwork of this map is uninspired. It's very blocky and detracts from the rest of the mod.
2. The voice actress was, at times, difficult to understand.
3. The transitions between levels wasn't properly explained in the beginning. You're in a very gritty and creepy place, then this thing opens up. I can honestly say that my first thought wasn't, "Why don't I go through that weird portal thing?"
4. Certain areas could have been optimized better.
5. The voice actress's lines looped too often.
6. The plot of this mod is very, very, very open to interpretation. A solid story is almost nonexistent.
ODDITY: While playing, I detected many political undertones concerning capital punishment. It seems too prevalent to be unintentional, so I assume that the developer wanted to express his views on the matter to the player. I'm fine with the developer's viewpoint, but I'd rather have it stated somewhere that it's intentional/unintentional.
Overall, this is a very interesting mod and is completely worth the download.
