Pros:

- Good map
- nice open areas 
- Nice that you get gased if you stay in gun room to long (doesnt kill you)
-Challenging

Cons:

- Started automatically
- No warning to start
- A couple of invisible walls

Conclusion:

All in all this was a good map with some very creative moments, the automatic start without any warning because when i was playing it for the first time i was just looking round the map and was not prpared for the onslaught. but overalll it was a good map so I rate this map 75
