Pros:

Epicly fun
Good to train rushers
Fun to mess about with and find new strategies

Cons:

Impossible without cheating
Missing sky texture

Conclusion:

Nothing to change, a great map, though I would like a sky texture.

Pros:

Great fun
Good idea
Good improvisation, especially the door that opens after 2 minuites

Cons:

Easy to get swarmed when you open the door
Needs a shorter timer for the other barricades
Could have authenticity like the CoD version, ie use the force to repair barricades.

Conclusion:

Epic map, and a hell tonne of fun.Looking forward to playing it until I beat my score of 3 mins.
It would also be fun if you made it so the zombies came in waves somehow, would appreciate if you modified it so that it would be like that.
