Pros:

+ TF2
+ Just like the original
+ Can go into the Red spawn
+ Couldn't find any bugs and zombies ran around the map fine
+ Very good weapon placements
+ Survival is fun

Cons:

- In the Red spawn area, you can shoot through the glass and zombies can't hit you through it. (Balance issues mainly, not going to deduct points)

Conclusion:

I haven't played it on Co-op yet but Survival is flawless on this map. Very well done!

Pros:

+ CSS
+ Dust 2
+ Just like the original map
+ Zombies can spawn outside the borders of where the player can go
+ Fun

Cons:

- Skybox messes up sometimes, goes black
- Some textures are still the purple and black squares, like the milk carton
- Almost all the supplies are at the spawn
- Lack of weapons

Conclusion:

There are little bugs and there's a lack of weapon placement, but other than that its really good.
