This is a big enough map that the boundaries will develop for themselves - and until you have played it and know where the bomb sites are, it would be pointless even trying to describe a map limit because it would not make sense (you'll know what I mean when you have played it).
So, T's please advance with caution, CT's try to protect the two bomb sites. Sometime during the map you will engage the enemy :D Enjoy!
