the easiest method fr that map is just go out where yo got the flag, run to the middle area (the open area) there is a lift right there, take that when you have the flag, it will take you to the middle floor and then all you have to do is walk up the stairs right there to score it.
a good idea is to get 8 people together and play a math, instead of killing though just explore, find where all the weapons are, best routes from one place to another ect.. also when you walk by a place it will tell you the name of the place you are at on your screen (for exampl if i am walking on a ramp it will say blue ramp, or things like red lift, sniper walkway ect..) these are good call outs to learn. I played the arena gametype and they were all serious players calling out everything by name ect.. and so i tagged along for a bit and learned the map lingo by them also.
