Part of my Half-Life Fact Files series: youtube.com/playlist?list=PLDmcwfn8y0lMtlqcpUhggk0FB1EC2i3iB

This short installment looks at the history of Half-Life's cut alien breeding and moss growth, a saga spanning over half a decade that still remains open to this very day.

Credit to Barnz for a majority of the research.
