Uh, it kinda continues from the previous map, but it has some different elements.
And no more instakill pigcops either, though expect enemies to still pose a threat, in particular plenty of lizard troopers to deal with, i guess.
Else you could take a look in it by using mapster if you're really curious, i guess? Thats what i sometimes do. :P
Well, in short, i'd say its an improvement over the first one. Though yes, it kind of is a part 2 of the map. If you didnt like the first one i'm not sure if you'll like the second, but worth a try, no?
Ah, and didnt have room for this screenshot on the first post. I'll just put it here.
Mind you, most of the map is inside, and in uh... corridors and other thin places, it still offers a interesting firefight with lizard troopers though. They like to teleport and hit you in the back, if they can.
