Pretty awesome map, and I love the theming! I enjoy it when multi-stage maps limit it to 2 stages. I played this map more than a few times on a pub server I moderate with 30-32 players at a time, and I believe it works pretty well with many players. The only shame is that it seems more often than not, we never got to the second stage. Not sure if this means the map's catered towards the Defenders, or if it was simply a coincidence and the Attackers were having a bad time. Either way, it's a lovely map!
But the map is too small...
