Shocking Dark (aka) Aliens 2 (1990)
Everybody was bootlegging this one for years, as "Aliens 2", "Terminator 2", and the classic "Alienators". In a near future Venice that is sinking away, various soldiers for "The Tubular Corporation" try to cover-up and destroy evidence that the art museums are being looted for their treasures. Nearby genetic scientists unveil their latest mutant creation, which promptly escapes and hides in the ruined city. Eventually, the soldiers get help from the mysterious "Samuel Fuller", quickly revealed as a cybernetic soldier, out to capture and exploit the mutant creation. Soon, it's all-out chaos with the monsters fighting soldiers,with cyborgs out to profit from it all, for the Corporation. Jenna Ryan is great as the prerequisite tough soldier, and should really get better roles. It's got a piece of everything, and pits it all against each other, until a spacey psychedelic climax of cosmic proportions. I have it as "Shocking Dark", with a brief shot of a still that says "Alienators"
