Finding the Garden of Eden

 is a Fallout 3 quest. It is also a PlayStation 3 Trophy and a Xbox 360/PC achievement

Summary
Retrieve a G.E.C.K. from Vault 87.

Enter Vault 87
Depending on your choice during Picking Up The Trail, you either have to fight your way through Murder Pass to the vault door and enter or talk to Joseph in order to hack the terminal to enter Vault 87.

Find a G.E.C.K.
Both entrances of Vault 87 lead to the Reactor Chamber. From there, you proceed to the Living Quarters, then the Test Labs. There, you eventually encounter a literate Super Mutant named Fawkes who asks to hold a conversation with you over the intercom. Fawkes explains his upbringing in the vault and how he has become literate and civilized through continued access to the vault's database. Fawkes promises to retrieve the Garden of Eden Creation Kit from the irradiated halls above if he is released.

The radiation level where the G.E.C.K. is stored is extremely high. You can proceed in one of two ways:
 * Attempt to get the G.E.C.K. without help. If you choose to do so, sufficient protection will be needed to resist the radiation and/or some RadAway. There is an Advanced Radiation Suit in a locked storage room on the way to the G.E.C.K.
 * Release Fawkes, who will assist you in both combat and obtaining the G.E.C.K., thus fulfilling the objective of the quest. See Free Fawkes below.

The room with the G.E.C.K. can be found by going left from Fawkes' cell. If you release him, he leads you to it and will engage the remaining enemies in melee.

(Optional) Free Fawkes
Fawkes can be released in two different ways: either starts with going down the hall on the right, and into a maintenance room with 2 Super Mutants. There is a Fire Control Console here that can be activated to unlock all the cells, or a Hard terminal next to it that can be hacked to open his cell directly.

Attempting to unlock the door through the terminal next to his door or by picking the door itself will result in a message saying the door is jammed.

The rooms contain...
 * Room 01 - 3 dead people (2 Wastelanders and 1 Raider)
 * Room 02 - vacant (Centaur possible)
 * Room 03 - The only "dangerous" test subject, a nutty human named Sid in room 3. If you unlock the door through lockpicking, he may be spoken with, where he will babble insanely, including how everyone is dead and "it's all [his] fault", and to "get out of his head". If the door is unlocked through the terminal (be it his or the master one) or the Fire Control, he will turn hostile.
 * Room 04 - vacant (Centaur possible)
 * Room 05 - Fawkes

Once Fawkes is free, he will thank you, and hold up his end of the bargain. He will proceed to slowly walk to the room with the G.E.C.K., fighting any enemy Super Mutants along the way. Once he's there, talk to him again to get him to go retrieve the G.E.C.K. - he can be watched through the windows as he does this, or alternatively followed (talking to him during this will give an amusing comment). If you do not feel like waiting for him in real time, a 2 hour wait is enough to bring him instantly back to you.

However, if Fawkes is killed, the player will have no choice but to retrieve the G.E.C.K. on their own. Fortunately, the Super Mutant is very tough, and the only way it will happen is if the player does it. A notable way of doing so is to use the "Terminate Specimen" option on the Hard Terminal next to his cell. Doing this will result in Bad Karma. You can do the same to any of the other specimens, although without the Karma loss. If Fawkes is engaged and killed after he has picked up the G.E.C.K. but before giving it to the player, it can be retrieved from his corpse.

Escape from Vault 87
Unfortunately, even after all this effort you will be incapacitated upon attempting to leave the vault by a type of Flash Bang Grenade, and Colonel Autumn will show up with some Enclave soldiers, and take the G.E.C.K. from you. An exception to this is in the Bugs section below...

Followers
If you are accompanied by a follower NPC, they will not be with you after you have been incapacitated by the Enclave. Be sure to retrieve any equipment from them you do not want them to walk off with (as if they were fired) before this happens, or right after retrieving the G.E.C.K. You will not have a chance to re-hire your companion until after The American Dream. After re-hiring a companion they will have all the items you left with them still in their inventory, so it can be a good way to free up inventory space of non-essential items you want but wont need during your time in Raven Rock.
 * Butch DeLoria will return to The Muddy Rudder in Rivet City
 * Charon (Fallout 3) can be found at the ninth circle in underworld immediately after escaping from Raven Rock.
 * Star Paladin Cross will return to the Citadel and is able to be rehired.
 * Dogmeat will be waiting in front of Vault 101

A good way to regain lost items from your followers is to sneak attack them with the Victory Rifle and take your stuff while they are down. This has no loss of karma, nor will the ex-follower turn on you. You cannot take the armor off. This is useful when you had 2 followers from different karma zones, and do not want to commit karma giving deeds to reclaim your items. (Confirmed X360)

Completing this quest, and spawning in Raven Rock, will delete all extra companion slots gained through exploits. See Discussion tab.

Bugs

 * Fawkes may get stuck between a wall and a machine for a while when walking to the G.E.C.K. If that happens, the player can give him a shove to help get him out. (unconfirmed)
 * On some occasions, Fawkes will seemingly fail to retrieve the G.E.C.K., but it actually gets transferred into his inventory instantly. This seems to happen when he tries to walk up against something and finds his path blocked. (unconfirmed)
 * Occasionally, even followers you've left standing around somewhere will get respawned to their default positions after the Enclave captures you. You may even be able to hear Dogmeat's panting during the cutscene. (confirmed on PC)
 * Two G.E.C.K.s can be obtained. First retrieving the G.E.C.K. yourself, before releasing Fawkes, through liberal use of radiation reducing chems, and armor. The second by releasing Fawkes, and letting him retrieve one for you. (after the Enclave ambush at the end of the mission, you are left with one.) (unconfirmed)
 * It is possible to start this quest as soon as you leave Vault 101, if you do the Citadel glitch (get under map and inside) just speak to Scribe Rothchild to start the quest. NOTE: You don't even need to find your dad first, just head straight there!
 * It is possible for Fawkes to get stuck between a wall and the row of lockers. If so he will not be waiting for you, when you exit Raven Rock.  If this happens you can go back to vault 87.  Just walk around and he should pop up saying the dialogue he should have said when he meets you outside. (unconfirmed)
 * It is possible when exploring little lamplight prior to initiating this quest that the Reactor Chamber door which is normally locked will be unlocked. This allows the person to explore vault 87 and even aquire the G.E.C.K. (or two),Fawkes, and the enclave ambush. Quest completion and achievement follow suit. (unconfirmed)
