I remember a game based on the quake engine.
1. It had a mode allowing greenish scorpionoids to fight greenish 
spideroids and play capture the flag, and a base single player mode 
with lots of alien killing.
2. There was a contest connected with the game, and to enter, the 
owner had to take a screenshot of the hidden entrance to a secret 
level, and another screenshot somewhere on the secret level. If I 
recall correctly, the prize was an ultimate gameing PC (for that 
era - it probably wouldn't be all that impressive now).
3. There was a timed level, where you could pick up lots of gear, 
but were kicked out after 30 seconds or so, just like the "behind 
the waterfall" secret level in the later Quake 2.
4. The ultimate boss looks approximately like a big bloated 
immobile baby that spawns monsters. Shoot him enough, and a large 
wound appears, and gets deeper and deeper with more damage as 
layers peel away. Killing it opens a couple of barred gates leading 
to a spaceship to escape, and a wrap scene.
5. I keep thinking the name of the game was Shraak, but a search on 
Google doesn't get any hits for this, so it must be something 
vaguely like that.

I'd like to see any of the following. What is the right name of the 
game? Who made it? Were there any sites with pointers, maps or game 
support?
