hmm very nice map :D!
very nice details :D, but u should add a bit more textures :s. Lightning is great to :D!
some things, please add particles to the lava, to make it a bit more realistic (once they should replace the lava texture :P) and texture those walls at the lava, a bit more (now u taked a bricktexture, and putted a stone texture to it, looks pretty strange :s).
at gameplay, please add some more ammo, theres almost nothing in it (found only 4 shell, 3 grenade, 4 bullet, 3 rocket and 2 rifle suplies) D:! please increase at least each ammo with 1 supply more. Further, i really dont understand the place of the 10+, so easy 2 get :s?
theres a texturebug on 1 of the sides of the map, please fix it, looks a bit strange and unproffesional (i think u changed the gridsize when u were working tehre)...
sumtimes, the lightning is a bit strange, maybe u should add a bit more torches (like in the place with that teleport against a wall).
very nice details at the jumppads :D!
i dislike, that u used the "one way cube" D:, i heard there were bugs in it and it stands just strange at the theme :s. please try an other solution.
maybe its taste, but u should make the ladders a bit less big in the length, it gives the ladders a taller and nicer shape.
anyways, nice map! please fix all those things, then 5/5, for now, 3/5 sorry :s.
