Pros:

- Graphics are just excelent, loved them
- NAV very improved
- Bots less dumb than before
- Zombies spawn up till Hellfire without a problem
- Finale is amazing
- The feel until hellfire was great

Cons:

- Buggy since Hellfire as hell, I got outside map at least twice. 
- No zombies at Hellfire, all of them die in fire, even at moments where you expect huge hordes you can't see any.
- Both Decissions Decissions maps (not finale) were lacking zombies, but the worst was elevator on 2nd DD map - practically no zombies, plus you could stop the elevator by being on edge.
- Some textures, by that I mean DD 2nd map first save room, had "ghost" issue - you could simply walk through it. I mean that incubator
- Laggy even on single player
- Sometimes floating weapons - especially weird I found chainsaw on hellfire which was floating in air... for no obvious reason...

Conclusion:

Yes, it is outbreak and it's great maps, but no it's not working correct - the fun stops at hellfire immidiatelly when you realise your task isn't to survive but to pick up stuff to open doors where u find stuff for other stuff and so on. Same with Decissions Decissions.
