Final Fortress

Pros:

I loved the environment, it was very well created.
Fun to play, lots of places to hold out.
Good AI
Good level of difficulty, not too hard, not too easy.
 Lots of oxygen/gas/propane tanks. 

Cons:

Tanks spawn almost instantly after another.
It's not for l4d2 yet. :)

Conclusion:

Overall, I was jealous. I loved this map, it was a beautifully created map, the fortress was excellent, the outside area was excellent, and the ammo was well spaced out through out the map. The game play was okay, the zombies took a little while to get to me, but that was okay. I wasn't swarmed by smokers/boomers/hunters, but once again, the tanks overwhelmed me. It was fun trying to run though, so that really doesn't matter. I loved this map, I really did, therefore, I will give it a 90/100.
