Starring Richard Keats, Mitchell Cox, Lisa Ann Russell.
In 2073 a hot shot time-travel scientist sends a probe back to 1973 only to alter the Earth's history which suddenly becomes ravaged by killer robots that look way cool but can't aim for shit. Now Sinclair and his gang of tuff guys have to fight the robots and somehow prevent the rampaging apocalypse they've brought upon themselves.
This straight-to-video schlock flick is often called a Terminator ripoff, with less plot and more guns. Yea, more guns than Terminator. More fire, more explosions, more robots. If you can find it, it'll probably only be on VHS.
