Elliott Tercorien

, serial number 3477809, is a non-player character in the Fallout 3 add-on Mothership Zeta in the year 2277.

Background
Tercorien was a doctor working in Washington, who was drafted into the army just prior to the Great War. Much to his dismay, he was shipped to Anchorage, Alaska, after receiving training in cryoscience. Attached to the 108th Infantry Battalion, he and his team were responsible for patching up soldiers wounded in combat with the Chinese.

It was there that he and his medical team were abducted by Mothership Zeta. Only two other members of his squad survived the experiments until the Lone Wanderer found them. They were kept frozen separately near what appears to be a surgery with the rest of his squad's bodies. If the player revives the other two squad members before Elliot has had time to restore their memories then they become hostile. Elliot can either put them out of their misery or revive them. If they are revived, they only have a limited amount of time before they die.

Effects of player actions

 * 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 after every 3 hours. This will provide an unlimited source of Cryo Grenades and Mines.
 * 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, he remains aboard the Mothership, admitting he's got nowhere and nothing to return to. While he is onboard, he will continue to salvage and store up alien weapons. 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.

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

Behind the scenes

 * His name is a reference to the television show Scrubs; Elliot Tercorien's name is a portmanteau of the character names Eliot Reid, Christopher Turk, and John Dorian, all of whom are also doctors.
 * When you ask him what the aliens want with Earth, he 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 Snacthers for his idea of clones wanting to replace people on Earth.

Appearances
appears only in the Fallout 3 add-on Mothership Zeta.

Bugs

 * After reaching the command deck, his forehead may become transparent. If the player goes down to the Capital Wasteland and then back to the Mothership, his forehead will reappear.
 * If you attack Toshiro Kago who at this point turns hostile, Elliot may run away and disappear for good.
 * After reaching the main deck of the ship and engaging the other space ship, if you are hit during the battle, Elliott may randomly disappear at the end of the skirmish. A possible way to fix this is to turn the power off, go to the Capital Wasteland, and come back several times.
 * On the bridge, his Assault Rifle sometimes becomes unbound to his body and hovers around a wall instead; mousing over it still labels the floating rifle as Elliot Tercorien.
 * While in Cryo Storage, activating the first Cryo container while Elliott is next to it will freeze him allowing the player to take 500 5.56 mm rounds from his person. He will then get up again.
 * It is also possible to make him leave the ship and enter the Capital Wasteland if he is made to flee. He will stay there indefinitely.
 * Sometimes Elliot will manage to path his way up onto a piece of rubble or debris and fall over the railing. The fall will kill him instantly, as he lands at the lowest level, making his corpse inaccesible.
 * Elliot may freeze after the time delayed death of Sgt Daniels and Pvt Beckett
 * After destroying the enemy ship and talking to him, it is possible that when you try to talk with him the dialogue box will be blank and the conversation will end quickly.
