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 three 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.
 * If your follower is Charon, you can ask him to retrieve the G.E.C.K. for you: as a Ghoul, he is immune to radiation. If you accepted to free Fawkes before asking him, however, Charon will refuse, stating that his contract covers only the fighting and that he is "nobody's errand boy".

The room with the G.E.C.K. can be found by going left from Fawkes' cell. If you release him, he leads you (slowly) to it and will engage the remaining enemies in melee. Fawkes is even more tough in this part of the game than he is as a follower, so you shouldn't worry about him dying.

(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 an Average computer 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 picking the lock, 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, allowing you to stock up on the mountains of Enclave Power Armor.
 * Butch DeLoria will return to The Muddy Rudder in Rivet City Butch will now follow you if your karma is not neutral anymore.
 * Charon (Fallout 3) can be found at the Ninth Circle in Underworld immediately after escaping from Raven Rock. You can take him back for free (you still hold his contract) and, of course, regardless of your karma. When you engage a conversation with him he will speak to you as if you had asked him to wait for you ("You return. Shall I join you once again?").
 * Star Paladin Cross will return to the Citadel and is able to be rehired. if your karma is now too low for her (neutral or bad) she will refuse to join you.
 * Dogmeat will be waiting in front of Vault 101 (beware however that he may die before you take him back).
 * Clover will be back in Eulogy's house in Paradise Falls, even if you killed everyone in town, including Eulogy. You can take her with you without having to pay and regardless of karma (as a slave she is blindly loyal).
 * Sergeant RL-3 will be waiting for you at Canterbury Commons. You do not have to pay to take him back, but your karma must still be neutral.
 * Jericho will be in Megaton, most likely Moriarty's Saloon. If Megaton is destroyed he will wander around the ruins. If your karma is now too high for him (neutral or good), he will refuse to follow you again.

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

 * While following Fawkes to retrieve the G.E.C.K., you can talk to him with a standard set of follower conversation options, and trade equipment with him. However, after he gets the G.E.C.K. for you, the talk options are not available any more - you lose anything you gave him. The next time you see him outside of Vault 87, he will have an empty inventory. (confirmed Xbox 360)


 * 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. (confirmed Xbox 360)


 * Even though Fawkes may be near "invincible", if the player moves through a path Fawkes cannot follow (over a ledge, jump, etc.) when first leaving Raven Rock, the player will hear Fawkes' Gatling Laser firing continuously and Fawkes may die. Upon investigation it seemed he was killed by a lone Yao Guai. This happened when traveling over rock ledge to the SW of Raven Rock. (confirmed PS3)


 * 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.


 * For some reason you may be able to hear Dogmeat's panting during the cutscene. (confirmed on 360, PC and PS3)


 * 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. (confirmed PC)


 * 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 acquire the G.E.C.K. (or two),Fawkes, and the enclave ambush. Quest completion and achievement follow suit. (confirmed on PC)


 * It is possible that after being knocked out by the colonel you never black out and continue looking at the Enclave soldiers forever. (confirmed on PC)


 * Not talking to Scribe Rothchild will affect your ability to get the first Broken Steel quest. (unconfirmed)
 * If you're wearing the ghoul mask or Chinese Stealth Suit, or each one respectivly, your game may crash after you black out. (confirmed for the Stealth Suit; wearing it caused me to keep staring at the Enclave soldiers, while taking it off succesfully led me to Raven Rock.)
 * Charon will glitch into always saying no, whether or not you choose to rescue Fawkes. (confirmed 360)
 * Upon getting the G.E.C.K you will be somtines unable to complete the quest, It will tell you to go between the test labs and the liveing quarters multipule times. (confirmed PC)
 * If you have Star Paladin Cross as a follower when getting captured, she might vanish from the game entirely instead of being back at the citadel (PC version).
