The more I play this map the more I like it. There is plenty of battle on the bridge for mega, and then around RA, and goes back and forth.

Hard to navigate and too many corridors. Only the main area for major battle. All happens while you try to get there. Little gameplay. Nice atmosphere though.

What is the secret to get the BFG? I know you need to go through the rings but I managed only once. I die every time I approach them and in any case I don't know how get past the wrong place.
