Inside bombsite:
CT's may enter the U-shaped corridor at the far end of the yard, but may not go up the stairs that would lead towards T spawn
Outside bombsite:
There are 3 entrances from T-spawn to the outside bombsite. CT's should not go into any of them.
All rules are off once the bomb has been planted.
