Tom Clancy's Ghost Recon Hints for GameCube
To Unlock all 12 heros
Finish the 1st 12 missions in campaign mode.....
Hit crouch then get up near a wall or rock.
Note#1:the best level to do this is the level with all the trains that are wrecked.
Note#2:If it doesn't work try again.
Note3:one time I did this and I was technicly flying...but I was easier to kill.
