Pros:

Extremely well mapped
Music and lighting is brilliant

Cons:

I found the very first area the best place to stay for the full 10 minutes - didn't feel the need to explore (and therefore appreciate the full mapping qualities)

Conclusion:

A brilliantly mapped level.  Only downfall i personally found was that the beginning area + the tower was enough to last the full 10 minutes with just myself and the 3 other bots.  I didn't feel the need to use any other area of the map during the survival.  This was just me though, I'm sure others have utilised the whole of the map..
