It is a top-down action/horror shooter (think DOOM-ish), where you are a guy trapped in a facility filled with... things. Can you escape "The Facility"? NOTE: This game is best played alone. In the dark. With the sound turned up.
I am immensely proud of this game. Even to this day, I still have a blast playing it. I really wanted to do more with it, but I lost the source code in a computer crash.
Fortunately, I did include a really easy to use, powerful level editor (with tutorial). So the game has unlimited re-playability as-is. I have considered creating and bundling an additional map-pack for the game, but I haven't gotten around to it yet. If you have the desire to assist with that, by all means let me know! For that matter, if you create [i]any[i] level, feel free to post it in here. I'd love to try it!
Interestingly enough, this was the last game I worked on, as it was this game that started my quest to develop a true AI.
Here's some screenshots to wet your whistle:

In game, fighting some things.

Level editing. Opening that door would be bad.
I hope you have as much fun playing it, as I did making it
EDIT: I realized that nowhere in the documentation does it say that pressing F1 in the level editor brings up the level editor help window. Just FYI.
