I took a look at the Beta2 version of the map...
First of all, the FPS dropped dramatically now, but it is still playable... I didn't really understand why it dropped, since u haven't added much detail, so I opened it up in the Editor to check the things... So, here are some of the stuffs I noticed...
*Imho, there are way too many Lighting Emmiters in the Skybox... I think u could remove some.
*Inphidel talked about the Windows at the Goals... I agree with that. It should look like the same as the others.
*The lighting is better now, althought it got a bit darker, but its no problem, since the maps world is dark. The Lanterns or whaterver they are, on the ceiling (which give red and blue light) still give that, light outta nowhere" feeling... should fix that imo...
*I see, u added a terrain mointain... But I only saw that in the Editor... I think this makes FPS fall dramatically, but I'm not a scientist. Imho, u should take that out, and make some static mesh mountains... And u should make them viewable, coz u don't see this one during the game.
*The bars, are good. Would be good if u add some Triggers, and give a Post hit sound so, when they get hit, u hear that sound. Would be nice.
Overall, the map is in good progress. And I think that small Terrainedited mountain should be removed... But in the end, the map will be nice

keep up the good work m8!
