1. In the first room with monsters, a bunch of ogros were pointing towards the wall. Basically this means that the player can just walk behind them and not be attacked. I guess this was intentional, so that it would look like the ogros are using the consoles, however
2. the consoles don't really look like consoles. This is an area in which you should've done better. You used textures that shouldn't be anywhere near a console. There are lots of good tech textures at the back of the texture list, use those instead.
3. You don't do anything with the quad. Might as well use a carrot. You could do so that the player grabs some ammo, grabs the quad, and gets teleported into an area with lots of monsters. This would also make the map a little longer because I felt it was
4. a little too short.
Nice idea though. I would really like improvement on the consoles, they just don't look good.
