"lets add UFOs, dinosaurs, giant space men, burning buildings, a few cars, a giant castle. ahh yes glorious"
I think it's pretty cool.
Bring back arguably the best map in the franchise, and just add some secondary shite in/on the buildings that doesn't effect the layout or gameplay of the map.
Alien movie set, dinosaur movie set, pirates movie set, and I believe medieval movie set, different each time you play the map could be any of them, which keeps the map a bit fresher IMO.
Something I think should be done with more maps, make them different each time, could be 1 of 5 designs so they don't get so stale so fast.
