Half-Life: Opposing Force - Save Warp to Skip First Engineer Autoscroller

This video shows a theoretically RTA-viable save warp chain to skip the ~1min sequence involving the first engineer door breach (map of2a3) in Half-Life: Opposing Force. Take it with a grain of salt, considering I am not a GoldSrc runner myself; at the least, I think it's worthy of further investigation.
