ok i was playing nc_battlegrounds and i found a secret when you shoot the ground. Then i found another secret if you go into the tip of the waterfall in the secret. then i tred attcking a preson in the first secret but i went through the ground, i then went walkign around and found yet another secret, the cell games arena. I then wanted to leave the cell games and the underground but i couldnt find the way back up, its like a glitch or something.what i want to know is how do i get back up thorugh the underground to the first secret? confusing...lol
yeah i made some mistakes on that map 
one if u target a person this is the first area ur in, and go flying stright into the wall (using that thing sweep) towards the uhh... place whats looks like this

fly towards the corner-> | -------------------
/ | <- hole
-------------------------| |--------------| in the
| ---------------------| | ---------- | ground
| | ^ | | | | | lol..
| | | | | | | |
| | there.. | | | | |
| | <-cave | | -------- |
anyways if u fly stright towards some where around there, and hit the right place u will go thou the wall and i dono how that happened.. i hope that shows u the right place...
*edit*
that didnt come out right Lol
well just fly towards the place where the pond or 'water' place is into that wall.. hopefuly u can find it and u can go flying thou it its pretty easy ive gone thou it like 7 times...
there is 3 secect area's to get to one u have to go to one off the other secect places and find another secect to go to that one, but i guess going under the map will count as a secect place to then so theres 4 lol
in the arena go along the sky wall to wards one off the cliff there is a whole in the ground lol... where u can go down...

http://www.freewebs.com/csdc/nc_battlegrounds0005.JPG thats where u fly towards when sweeping and u can go under the map
http://www.freewebs.com/csdc/nc_battlegrounds0007.JPG this shows the way to the water fall and the arena yes the water fall part was stolen from the DBZ game from PS2 tats where i got that idea...
http://www.freewebs.com/csdc/nc_battlegrounds0008.JPG this one shows the part in the arena where theres a hole in the ground and u can go under the map.
http://www.freewebs.com/csdc/nc_battlegrounds0009.JPG this one here shows the way to the pond or water place.. that part is in the arena secert area...
the other way to get the the water place or pond or what ever is going into the water fall place and go into the water fall where it starts up the top and go down the long path. intill u reach it.
