Pros:

Original final, and challanging way to the final area.
Nice use of crescendo events(sometimes).

Cons:

Realy bad texture work, i sure hope this is not your final version of the map. The bots really got alot of problems going thru this map, the elevator on the first part is bugged, it stands "Wait for everyone to be ready first" and it wont start! EVEN WITH ONLY ONE PLAYER FFS!
Some of the traps are way to sudden and can ruin gameplay really fast. Some of the areas the bots get stuck and you cant get back and help them (map 2 if i remember correctly, had some real problems with the NAV files. The bots got stuck a little back from the saferoom, i couldnt go back as of the rails which blocks you from returning, and the bots coulndt move nor get dmged by infected. A little bad lightning work on some places. And in the begining the bots could not move down and special infected spawned up there after the saferoom opend.

Conclusion:

Ok map, really needs some more work to be a good map, lots of bugs and glitches, annoying neverending crescendos, lasers going off with no warning at all and holes in the textures, but not in the map. Overall an 47, and being pretty generous now. Go back and re-work on this map and realese a new version with bug fixes.
