Liberty Prime

Liberty Prime is a U.S. Army pacification robot. He is put back into service by the Capital Wasteland Brotherhood of Steel after they find him in the basement of The Citadel. (This is, presumably, the "technological marvel" mentioned in the Brotherhood's faction profile, and the unknown super weapon referenced in one of the newspaper cuttings that appears in the game.) He was originally designed to aid American troops in the liberation of Alaska from communist China. However, he was not completed on schedule, and America was forced to fight a long bloody battle using their other secret weapon, the more successful and reasonably-scaled Power Armor. Liberty Prime would finally be completed by the Brotherhood of Steel in 2277, upon which the massive robot led a Brotherhood attack against the Enclave at the Jefferson Memorial, ironically mistaking the Enclave troops for a Chinese invasion army and spouting anti-Communist propaganda statements throughout the battle.

He requires a massive amount of power to operate, as the Brotherhood of Steel was long unable to power him properly even with the advanced tech discovered inside the Pentagon. His large backpack holds a seemingly inexhaustible supply of Mini Nukes, which he can remove and hurl at enemies like a quarterback throwing a pass. He is also equipped with twin head-mounted lasers. His massive size and strength count as weapons too: he is endowed with strength befitting a forty foot tall robot, and can rip anything in his path to shreds... if he doesn't step on it first. He also appears to have an Energy Shield, as he can sustain massive amounts of damage and short out energy barrier fields by forcefully walking into them. Finally, to inspire his allies and demoralize foes, he constantly spouts anti-Communist phrases (like most of the servitor/combat robots in the game, he seems unaware that any time has passed between 2077 and the present).

Through the computer terminal at the foot of the Liberty Prime, it is revealed that the project was commissioned by General Constantine Chase, and is a joint effort between the U.S. Army, General Atomics, and RobCo.

It would be a difficult proposition, at best, for the player character to get through the gauntlet of Enclave troops, Power Armors, and (armed) VTOL aircraft without the fire support of the giant robot, and it is impossible for the player to proceed further towards the Jefferson Memorial after the Enclave secures it (without exploiting glitches in the program), as the area is closed off by several sets of otherwise impenetrable force-fields that only Liberty Prime can neutralize.

Characteristics
Liberty Prime is a massive, forty foot tall robot stored in the basement below the Citadel. It is humanoid in shape, and somewhat resembles the title character of the movie The Iron Giant, but possesses the head (and laser vision) of Gort from the 1951 version of The Day The Earth Stood Still.

Along with his laser weaponry, he is armed with portable nuclear bombs and an energy drainer to deactivate energy barriers.

Appearances
Liberty Prime appears only in Fallout 3.

He is first seen in the lab underneath the Citadel in his inactive state. The player can learn information about Liberty Prime as well as hear some of his dialogue by using a nearby computer terminal.

During the events of Take it Back!, the Brotherhood of Steel (with the cooperation of Dr. Madison Li) manages to reactivate the robot, who then proceeds to clear the way for Lyons' Pride to the Jefferson Memorial, where he remains until the end of the game. Despite the sense of urgency imparted to the player to protect him in this mission, Liberty Prime appears to be indestructible and entirely capable of defeating the Enclave all by himself with little or no help from the player.

During Broken Steel, Liberty Prime joins the player in the battle against the Enclave during Death From Above. After the Enclave initiates an Orbital Strike, Liberty Prime is destroyed. His head is later taken back to the Citadel. Similar to Deputy Weld, his head can be activated and he will say some of his anti-communist phrases, albeit scrambled and garbled.

Trivia

 * The American Soldiers in the Operation: Anchorage DLC use some of the propaganda slogans Liberty Prime recites continuously.
 * Liberty Prime was thought to be a possible reference to Optimus Prime, of Transformers fame, as their voices sound remarkably similar, and Optimus Prime's most common motto is "Freedom is the right of all sentient beings", similar to Liberty's patriotic battle cries of pro-Democracy. However, according to an interview in 1UP Emil Pagliarulo denied any intentional relation between Liberty Prime and Optimus Prime; it's a completely made up name, created long before the 2007 movie made Optimus Prime a 'famous' name again. Pagliarulo admitted he could have made the reference subconsciously, as he sometimes is known to do.
 * Liberty Prime is not the first giant robot that Bethesda Softworks has created as a major plot element: The brass golem Numidium has featured prominently in The Elder Scrolls II: Daggerfall, and its successor Akulakhan was also featured prominently in The Elder Scrolls III: Morrowind. Similarly, the ending to The Elder Scrolls IV: Oblivion also has a giant humanoid (Mehrunes Dagon).

Bugs

 * It is possible that Liberty Prime will have path issues on the first large bridge you cross, and get "stuck" requiring you to reload a save. Sometimes these path issues can be resolved by destroying the junked cars on the bridge, or by fast-traveling to the Citadel (only an option if you are out of combat).  If he gets stuck behind a car simply blowing it up will work; however there is a possibility an Enclave Vertibird will crash in his path, in which case nothing but a MIRV will budge it. Sadly this makes all Brotherhood forces except Sentinel Lyon hostile towards you.
 * Liberty Prime will sometimes simply not move from his starting location.
 * The player can make Liberty Prime hostile to themselves by shooting at it for a while, but can freeze if too much damage is done, possibly because of the disruption to its routine.
 * Once you complete the Broken Steel DLC, you can find Liberty Prime's severed head in the Citadel, but at the same time you can find it on the ground at the Satellite Relay Station.

Quotes
Liberty Prime has many quotes, filled with overly patriotic and anti-communist meanings. Many of the quotes are grandiose in nature and can be seen as comic relief. Some of the quotes can be seen as hypocrisy or contradictive such as "EMBRACE DEMOCRACY, OR YOU WILL BE ERADICATED." which contradicts free choice in a democracy and DEMOCRACY IS NON-NEGOTIABLE." contradicts itself since a democracy is supposed to be based upon negotiation, freedom and choice.
