Played it and wrote a short review
Level Design
Top-notch. Loads of detail and barely detracted from playability (I snagged me toe on a few pieces of scrap, but nothing serious). The enviroment was immersive and the wall textures were sharp and crisp.
The only thing that I noticed was in the start room was a pointless dead-end had there been no damage caused to the place. Obviously, when you jump down through the collapsed supports there's a door, but if those supports had been in place it'd strike me as a pointless room.
Nevertheless, the level design was the strongest part of the game.
9/10
Presentation and Sounds
Loading screens were nice and unique, along with a custom pointer. The music on the loading screens and the sounds within the game were great, the new sounds on EAI's M9 was nice as well. I think these really added to the immersion.
I tihnk the lack of voice acting was dissapointing, but it's only a taster level, so I can't ask too much. Hope to see voice acting in the full game tho'.
7/10
Gameplay and Playability
Yeah, so this was pretty high as well. The game ran smoothly at a constant 60fps, which is great as most fpsc games run at 45-50. It was an enjoyable ride, there were no bugs, no falling through the floor and the enviroment was well-lit. The enemies were pretty cool as well, although I didn't get scared, but that's probably just me (sitting in a brightly lit room with my brother playing music next door

). The enemies were pretty tough and I liked the ticking geiger counter and death if you enter the radiation river. The enemies were easy to own from a long range. Sadly, gameplay wasn't different from the average FPSC game. It's the level design however that made it stick out from the average game on the forums and still an enjoyable experience.
7/10
Misc. Points
Yeah, so I liked the lighting very much, as well as the thin fog that surrounding areas of the game. Choice of media fitted excellently. I think Scripted events was a bit lacking. But, as I've mentioned before, It was a small teaser and I can't ask much.
4/5
So, my total mark:
27/35
Hope I didn't seem harsh, it was really fun and above the average FPSC game
