Pros:

New kind of survival gameplay, levelling system
Each round is always different
Simple yet consistant design

Cons:

Bots are sometimes useless
Lack of detail
Flickering skybox

Conclusion:

When this map was originally released I couldn't play it due to texture problems/crashing and have been waiting until the problem was fixed. Finally, it's been fixed and this map was worth the wait... the concept is brilliant and gameplay is addictive but I feel both have only been touched on briefly. The overall design is simple and there is a lack of detail but these factors fail to affect the overall experience negatively. I hope to see more maps like this released, but taking the concept and gameplay even further.
