Elerium-115

Elerium, otherwise known as element 115, is the source of all alien power. Mined from reserves near Cydonia, it can be used for just about any purpose. It cannot be synthesized on earth.

Obtaining Elerium

You can only obtain Elerium during UFO Assaults, or Alien Base Assaults. If upon starting a UFO assault you find the UFO Power Source to have been destroyed (as a result of a crash landing), the Elerium will surely have been destroyed as well. Perhaps the most efficient way to gain a stock of Elerium is to find an Alien Base and attack the Supply Ships as they land nearby. Leave the base intact to attract more supply ships, as the Elerium is worth more than the score penalty.

Aliens attacking your base will sometimes bring Elerium along.

UFO Power Sources are cylindrical orange machines which can be broken open by plasma fire to retrieve a purple ball (the same graphic as a Stun Bomb on the ground). It's worth 50 points of Elerium. Elerium is very fragile, and can be destroyed easily with explosives. For more on securing Elerium from UPSs, see UFO Power Sources.

Base Power Sources are spherical or ovoid red machines that also contain Elerium in their base. They are explosive but can be shot away. You can raid a base without having to win the mission, just have a soldier carry the Elerium back to the entry lift and then abort the mission.

If picked up, Elerium appears on the Inventory Screen as some small yellow crystals using a 1x1 inventory slot, and weighs (?).

If you win the mission, Elerium is extracted and recovered automatically.

Uses

Don't sell Elerium. Although you do have the option to sell your Elerium, this is highly unrecommended. It is used to fuel the Firestorm, the Lightning, and the Avenger. It is also used, in varying amounts, to manufacture most Alien Artifacts, Flying Suits, and various other technologies. Given that you can only obtain Elerium in the battlefield, selling it is not a good idea. If you choose to, it will fetch you $5000 per unit.

Background

Ununpentium, the temporary name for synthesized element 115, was only created briefly in atomic laboratories in 2004 and is not the subject of much research. However UFO 'researcher' Robert Lazar made several claims about E-115 in the 1980's. For example, it would be the only element that had a gravitational field extending past it's own atomic 'shell'. This deviance from the normal rule would be so significant that perhaps the technologies seen in the X-Com Series could become a reality - anti-gravity devices used for both flight and particle acceleration.

Trick: When using X-COMUTIL to generate UFO maps, you are more likely to get intact powersources, especially on the larger UFOs like Supply Ships.
