Instructions
Load the multiplayer for "Grand Theft Auto San Andreas" and enter the Hydra Blast server.
Travel to the Area 69 bunker in Bone County, San Andreas.
Head down to the radar room in the basement area, where you will find a computer terminal and a red outline in front of it. Step into the red circle to open the nuke menu.
Select the nuke of choice and the city to use it on. The ICBM Nuke costs the most, $10 million, but will send a bomb to every city.
Defend yourself, with guns or any other means available, against the armed guards and other players who will try to kill you. Should you die the nuke will not launch. Once ready, a server message will alert you that the nuke has gone off.
