Pros:

A great challenge with friends
Great defensive positions
Interesting features like the big gun on the tower and the cage.

Cons:

Needs to be made so bots are not useless
No chance unless you have players
Gets laggy sometimes

Conclusion:

Overall, I really enjoyed this map. I thought that it was a great challenge with my group of friends and it took a lot of time to work out a suitable tactic between the four of us. It's something you'll replay and replay until you get the building complete. I would strongly suggest for you to get this maps. Very good!
