The Big Gun is the primary defense system of the planet Stroggos. It is capable of destroying larger ships in orbit, or frying smaller ships in the atmosphere through EM pulses. Its destruction would be a major blow to the Strogg war effort.
The player enters the Gun's control area, which is heavily guarded by Strogg defenders (including a deadly Hornet), but houses the button to lock down the laser guard and allow aerial bombardment to destroy the superweapon for good.
