Elliott Tercorien

Private Elliott Tercorien, serial number 3477809, is found abducted and held in a stasis chamber in Mothership Zeta's engineering core in 2277.

Background
Dr. Tercorien was in the U.S. military, serving just prior to the Great War. He doesn't recall the exact events that led up to his abduction and has no memory of the time between then and now because he was kept in cryogenic stasis the entire time. Elliott is good with technology and medicine. He's not so good with people, or bravery, or sobriety. While he's capable of defending himself due to military training, he goes to great lengths to avoid getting in situations where defending himself might be necessary.

Relationships
His unit:
 * Sgt. Daniels (active)
 * Cpl. Rheems (K.I.A.)
 * Cpl. Spurlock (K.I.A.)
 * Pvt. Mears (K.I.A.)
 * Pvt. Dawkins (M.I.A.)
 * Pvt. Beckett (active)

Quests

 * Among the Stars: You have the option of bringing Elliot Tercorien with you as a companion to the cryo lab to help out. Elliot can either put the other two surviving members of his squad out of their misery or revive them. If they are revived, they only have a limited amount of time before they die.
 * This Galaxy Ain't Big Enough...: If Elliot survived his section in Among the Stars, he will help in the last battle by keeping aliens off you while you fight the other mothership.

Other interactions

 * If the Lone Wanderer has any alien biogel, Elliot has the ability to modify the regular biogel into adapted biogel. The adapted biogel has a much higher healing capability but still contains the either helpful or nasty side effects of regular alien biogel.
 * After taking him into the cryo lab, he will gain the ability to make cryo grenades and cryo mines. The first batch consists of 3 of each and can be taken after 1 hour. The player can then receive another 2 cryo grenades and 2 cryo mines every 3 hours. All conversation options which allow the player to request cryo mines and cryo grenades are only available while Elliot is in the engineering core section of Mothership Zeta.
 * It is still possible to get cryo mines and grenades after the space walk, by going through the teleporter after the Compression sequence and asking him to make some while in the Engineering Core.
 * After the This Galaxy Ain't Big Enough... quest is completed, the player can return to the Mothership at any time and ask for weapons. If Elliot has some stockpiled, he will provide you with what he has in his cache. He gives either alien atomizers, alien disintegrators, or shock batons, and it is common that he will give multiple weapons at once. After giving away the weapons, the player will have to wait or return in another few hours for him to salvage more.

Effects of player actions

 * Assuming you befriend him, he can use his medical skills to change the formula of Alien Biogel, making it into the much more potent Adapted Biogel. If he survives an expedition into the ship's Cryo Lab, he can also construct Cryo Grenades and Mines. After quest completion, Tercorien begins to stockpile weapons, giving them to you when you return and speak to him.

Inventory
* These weapons are given to Private Beckett and Sergeant Daniels.

Appearances
Private Elliott Tercorien appears only in the Fallout 3 add-on, Mothership Zeta.

Behind the scenes
When you ask him what the aliens want with Earth, he tends to get inconsistent, and will refer to multiple explanations for alien encounters from various sci-fi shows, such as Independence Day for the resource consuming theory and Star Trek, for his idea that the aliens seeded life on Earth, and even Invasion of the Body Snatchers for his idea of clones wanting to replace people on Earth.

Bugs

 * Elliot may suddenly stop making cryo grenades and mines. The dialogue option will still be present, but choosing it will result in Elliot saying "not yet, still working on them" even though time has passed.
 * The bug's cause hasn't been identified, and only a small number of potential fixes are known.
 * Loading a save that was made before the bug occurred should fix the big.
 * Uninstalling and reinstalling the DLC may fix the bug, but may also cause numerous other bugs.
 * Sometimes, waiting in one-hour increments may cause Tercorien to start creating more cryo weapons.
 * Waiting for a short time and letting Tercorien walk around a bit may also prompt him to build more cryo weapons.
