In GTA SA go to Military base, go underground, Operation Blue Hell.
didn't know there was a hole in the airport. infact i dont know where the airport is.
It's near the beached ship over by the club with rainbow lights
There was no club
I finished operation blue hell. Just go to San Fierro and go to that triangular building, there is a hole under that is a portal to Blue Hell.
in the second to last picture it looks a bit.... odd
LMFAO
