From CT spawn there are three exits:
1.0 If you exit CT spawn under the SHOWS sign and into the bus station, then from this bomb site you may traverse up the green steel I-beam walkways and pass along them UNTIL the walkway opens out with a small landing on a concrete ledge on your right. From this point you overlook the road.
2.0 If you exit CT spawn by going up the stairs towards the underground road then you may move up the roadway until the final exit back into the building complex on your left. From this point you start to see around the corner and outdoors.
3.0 CTs can leave spawn and enter the train station. They may stay in the station complex, but may not go up the large stairs at the far end of the station, leading back to T spawn.
Sheeesh - that was the most difficult to describe yet.......
