Let's Play The Ultimate Doom - Part 9 - Phobos Anomaly (End of Episode One)

We reach the source of high energy readings coming from the base. We're greeted with two demonic Barons of Hell. After killing them, we take a portal to a trap where we are seemingly killed off. We end up at the lost Deimos Base, but that's impossible. We were just massacred by horde of demons and possessed soldiers. There's more going on here than you think. We'll find out in the next episode. This level was intended to be longer but was cut down. The uncut version of this level is downloadable somewhere. Look it up.
