This is reposted from a different site about the map, hopefully it will help anyone who is confused about it. Feel free to leave comments and whatnot.
As attacker, there are 3 routes from Spawn 1.
Around the left, around the right, and the shortcut through the middle. All of these meet at the area with the first intel.
Now, there are 2 paths. You can go to the left of the red building, or go under the archway. If you go under the archway, to your left is the second capture point as well as another exit for your SECOND spawn. Take note of this later. This middle path turns right, faces the bridge. The second intel is across the bridge. You can also go up into the red building from here.
If you go left of the red building, there's a ramp that goes to the top floor. You can either:
1) Go into the vent and drop off the right. This takes you into the "Blue Building". More on this later.
2) Drop off the front and rush the bridge, just like the people on the bottom.
3) Run around the left and get into the water.
The water has a ramp that leads up to the right side of the second intel.
Now, the Blue Building has a sniper/sentry ledge with an overhang shortly after you enter, then there's a left turn (behind the intel) and another sniper ledge. BLU spawns on the bottom floor of this building, initially.
Once the second point is capped, both teams move to their second spawn. This means RED gets to control the front side of the Blue Building, which has a path on the top floor that goes to the top ledge overlooking point 3 (turn left from the entry) as well as a path that comes out the side wall of the 3rd intel area (turn right from the entry).
The third area is to the attacker's right of the 2nd intel. This means there's a total of 3 paths to it- one main path and two side paths.
The 4th area is behind the 3rd, and there's only the one path to it; however, once you're in it, there's exposed ductwork (seriously, ductwork on the OUTSIDE of the building? What lousy HVAC engineer is this?) that gives you several other options for grabbing the intel. Stay out of the cow pits, they're instant death.
In summary:
RED Capture Point 1: In front of their spawn
RED Capture Point 2: Behind the Bridge and second spawn
RED spawn 1: Front of the map.
RED Spawn 2: Left side of the bridge, in the Red Building
BLU spawn 1: Bottom floor of the Blue Building
BLU spawn 2: Back of the map, behind intel 4.
BLU intel 1: second middle area, before you get to the RED building. Just in front of the wall.
BLU intel 2: Across the bridge.
BLU intel 3: In the back bunker of the area to the right of the bridge.
BLU intel 4: Far back of the map. In a bunker just in front of the BLU spawn.
