Liberty Prime

Liberty Prime is a unique U.S. Army combat robot that was found and brought to working order by the Capital Wasteland Brotherhood of Steel in 2277.

Background
Liberty Prime's original purpose was to aid American troops in the liberation of Anchorage, Alaska from Chinese invaders in the year 2077.

The computer terminal in the Citadel Laboratory, near the feet of Liberty Prime, reveals the project was commissioned by General Constantine Chase as a joint effort between the U.S. Army, General Atomics International, and RobCo Industries. However, problems with the power system led to delays, and Anchorage was ultimately liberated in a much longer and more costly battle using the US Army's other secret weapon: the T-51b power armor.

Roughly two centuries later, Liberty Prime was finally pressed into service by the Brotherhood of Steel after they discovered it in the basement of the destroyed Pentagon. The Brotherhood modified its targeting system to perceive Enclave forces and super mutants to be Chinese communists.

Liberty Prime requires a massive amount of energy to operate, and the Brotherhood were initially unable to power him properly, even with the advanced technology discovered inside the Pentagon. Eventually, with the aid of Doctor Li, the BoS solved the problem.

Liberty Prime was the Brotherhood's trump card against the Enclave, marching on Project Purity and effortlessly destroying the Enclave defenders entrenched there. For two weeks afterward, Liberty Prime fought battles against the Enclave, but was eventually destroyed by an orbital warhead bombardment. Liberty Prime's remains were recovered by the Brotherhood and, though it would take months—or years—to do so, they set about rebuilding and upgrading him.

Liberty Prime fires twin, head-mounted energy beams, similar to Tesla cannon, and can kill many Enclave soldiers in a single shot. His backpack holds a seemingly inexhaustible supply of explosives that he hurls at enemies with unerring accuracy. These munitions detonate on contact, in a manner similar to a mini nuke, but with several times the explosive power. His massive size and strength count as weapons too: he can crush or rip to shreds anything in his path. He can sustain massive amounts of damage, and defeat energy barriers by walking into them. Finally, to inspire his allies and demoralize foes, he constantly spouts anti-communist phrases and declares that American democracy cannot be defeated. Like most of the robots in the game, he seems unaware any time has passed between 2077 and the present or, more accurately, that any cataclysmic or world-changing events have transpired.

Quests

 * Take it Back!: The Capital Wasteland Brotherhood of Steel, with the help of Dr. Li, manages to fully power the robot. With the pressing need to reclaim Project Purity, Elder Lyons orders Prime deployed without proper testing. The giant robot makes its way to the Jefferson Memorial, destroying Enclave energy barriers, vertibirds, and troops en route. Once there, Liberty Prime assists the Brotherhood in guarding the building's entrance. It remains there for the duration of the quest.
 * Death From Above: Liberty Prime joins the Lone Wanderer in an assault on the Satellite Relay Station, an Enclave base located beyond the Rockland Car Tunnel. After the Enclave initiates an orbital strike, Liberty Prime crawls from the wreckage and initiate its self-destruct sequence to prevent its capture by the "communists". Its head, feet, and what appears to be a forearm are taken back to the Citadel. Similar to Deputy Weld, its head can be activated and will play back some of its anti-communist phrases, albeit much more garbled than during Take it Back!
 * Getting Ready for Prime Time: At the conclusion of Broken Steel's main quest line, Scribe Rothchild vows the Brotherhood will rebuild Prime, but it might take months or even years. He asks for help in scavenging sensor modules and cameras.

Other interactions

 * Liberty Prime is first seen in the lab beneath the Citadel in his inactive state. The player can gain information about the robot as well as hear some of its dialogue by using a nearby computer terminal to initiate a dialogue test.
