I think the first movie came out in about 87. i was about 15/16 then,

just looked up Radioactive Dreams (1985) the 2nd movie was in 85, that is the movie I was thinking about, Thanks! kaycee!

Looked it up :) movie #1, didnt even know they had a part 2
The Terror Within (1989)
It's the post-apocalypse, and the world has been changed by "the accident," a chemical warfare experiment gone awry. At an isolated subterranean complex, a group of people survives because they were able to get the antidote for the illness. They rescue a surface survivor from the gargoyles, who unfortunately had time to impregnate her, and when the "baby" is born and escapes into the ventilation ducts, they begin experiencing an attrition problem.
thanks to Kaycee again, she found both my movies

Thanks everyone,
