Taken from Earth perhaps a thousand years ago, there's no communicating with this man. And then, there's Toshiro Kago, a samurai who speaks no English. He's confused and scared, but actually quite useful, since he can turn all of those Alien Biogels you've been finding into useable Adapted Biogel, which exponentially raises its effectiveness. Private Tercorien was a US Army medic during the war back in 2077 that eventually led to a nuclear exchange, and therefore, quintessential MAD. When you claim you're on a ship, he claims you're lying, because the ship isn't rocking back and forth, and there's no sound of water. Paulson is a cowboy, probably from 19th century America. After all four are freed, speak to each of them to learn a little bit about them.
So while you don't necessarily have to free them, you ought to anyway. By doing so, you'll now have four humans from various points in the Earth's (relatively) recent past to help you on future endeavors during this second mission. By pressing a switch in front of you, in the middle of the four cryogenic chambers (two on each side), you can release them from their long static existence. Sally will have brought you to a cryogenics facility on the ship where four humans have been frozen in stasis for god-knows-how-long. This second mission begins fairly seamlessly with where the lengthy introductory mission concludes. 32 Caliber Rounds (M), Frag Grenade, Chinese Commando Hat, Chinese Pistol, Jet (x4), Buffout, Raider Painspike Armor, Power Helmet, Motorcycle Gas Tank, Energy Cell (M), Laser Rifle, Power Armor, RadAway, Stimpak (x2), Med-X (x3), Whiskey, Tesla Helmet, Mentats, Recon Armor Helmet, Microfusion Cell (M), Camera, Sensor Module, Recon Armor, Psycho, Combat Knife, Alien Log #2, Alien Log #4, Alien Log #5, Alien Log #6, Alien Log #7, Alien Log #8, Alien Log #11, Alien Log #13, Alien Log #16, Alien Log #17, Alien Log #19, Alien Log #21, Alien Log #25. 32 Pistol (x2), Advanced Radiation Suit, Flamer Fuel, Railway Spikes (M).
