The eighth level looks good except the shading is too weak from what I can see of it. This map is incredibly frustrating to figure out how to do properly. I can't find any weapons, I haven't figured out how to get the yellow key without luring a trooper near it and jumping off it's head. I found the blue key, but no blue lock. I did figure out how to get onto the wires and jump to the platform, squat-walk into the window where the switch is, open the elevator, and make a mad dash for the nuke button after obtaining the red key, which just happened to be in the room right next to the red lock.
I want to finish this map properly, but the lack of any weapons to defend myself while exploring is getting irritating to the point of where I just want to delete the game file and cut my losses. There are just way too many aliens to contend with to be able to stop in one spot for more than a split second before having to dodge all the lasers and bullets.
EDIT: Never mind. I found a pistol, a freezer, and the blue lock. I died about half a dozen times before I found what I needed to progress which doesn't say much for the game play of this map.
