Fallout 3 exploits

Scrap Metal exploit
Gain infinite experience, caps, and ammo (using scrap metal) (PRE-PATCH 1.7)

thumb|right|398px|Infinite caps, XP and ammo tutorial (working as of 8/8/2009) Using this exploit, the player can achieve infinite amounts of Scrap Metal. This allows the player to get unlimited Experience points, caps, Rad-X, Rad Away, stimpacks, Karma and 5.56 ammo from various characters who accept Scrap Metal (in dialogue).
 * The exploit involves a weakness in the "owned by" variable, which is attributed to every item in the game (sometimes having a value of "nobody"), and the small delay in inventory-management after some dialogue interactions, as well as an unsigned-integer underflow.

You need Scrap Metal for this exploit. 20 is a reasonable amount early in the game, but when bots start appearing in the Wasteland it shouldn't too difficult to find 60+. If you have Operation Anchorage, you can find quite a few on the way there and down in the actual Outpost. Crazy Wolfgang sometimes has 1 or 2. Moira Brown sometimes has 1. Random containers out in the Wasteland will have them. Bots will usually have one. Places like RobCo Facility, Robot Repair Center, and Dominic and Machete's House have a few laying around and in containers. There are various places in the subway system which will have a few, especially along the route to Galaxy News Radio.
 * You can perform this exploit at almost any time, but the earlier the better.

1. In order to do this exploit go to Fort Independence and talk to Protector Casdin, who will trade you items for scrap metal. Sell him all of the scrap metal that you are carrying. The more scrap metal you have, the more productive this entire process will be.
 * You must have an EVEN amount of scrap metal (divisible by 2), minimum 6.

2. Save the game, then pickpocket all of the scrap metal you just sold him. Make sure that you save before stealing it back because it is much harder to steal 100+ pounds of scrap than it is for just a few. If he catches you on this step, the glitch will not work properly.
 * Make another save after stealing the scrap metal, preferably in a different slot.

3. Sell him all of your scrap metal again, except for two pieces. Note that you give him two pieces of scrap metal at a time, so if you have 100 pieces of scrap metal, it's going to take 50 dialogue entries.
 * It is absolutely critical that you leave exactly two pieces in your inventory, and that you DO NOT EXIT OUT OF DIALOGUE until the process is complete. It is advised that you use pen/paper to keep track of the current amount.
 * If you exit out of dialogue, there will be a tiny window of opportunity to re-initiate dialogue before the scrap metal is removed from your inventory.

4. Immediately pickpocket him again and try to take something such as his Laser Rifle. He will catch you and there will be a indicator at the top left hand corner of the screen saying X number of scrap metal removed, then another X number of scrap metal. This step must be performed within seconds of the previous step, before the metal is removed from your inventory. There is usually less than 5 second opportunity.
 * If Casdin keeps attacking you when you get caught, then make sure you have very good karma. If he still attacks you then it's rumored to be because you have killed an Outcast member, in this case you can't ever do the glitch on that character.
 * Also if you have finished Operation Anchorage and killed some of the rebel Outcasts then it will not work (PS3 confirmed).

5. If done correctly. you will have an invisible amount of scrap metal in your inventory.
 * NOTE: Do not pick up any Scrap Metal or scavenge it off of robots. This will break the exploit and you will lose the infinite amount. It is best to proceed directly to the next step.

6. Now you can fast-travel to anyone who trades scrap metal, such as Walter in Megaton and trade scrap metal an infinite number of times. Doing this, you can level up from 1 to 20 (or 30) in about 30 minutes from Walter. He can usually be found in the Water Treatment Plant during the day, sometimes outside smoking on the ledge. The more scrap metal you use in this glitch the higher turn in options you will have with Walter.
 * If you wait several days, it's possible to return to Protector Casdin and sell Scrap Metal to him for his goods.

''(Tested on PS3, glitch still works as of 2009-OCT-18)'

Equipment Effect Stacking Exploit
After a follower equips armor, headwear or glasses that has some effect that increases an attribute or skill, its effect will stack every time you enter the trade window with the follower. You don't actually need to trade anything, just tell him or her you need to trade equipment then exit. Leaving the conversation entirely before entering the trade window again is unnecessary.
 * Damage Resistance is unaffected, and does not stack. The accumulated effects will stay with the follower even after you save and reload. Removing the item giving the effect will remove all accumulated effects from that item and put the follower back to normal.

This makes it possible for a follower to maximize skills or attributes they normally wouldn't be able to. As an example, Charon could get over 100 in Big Guns by applying this trick if he equips Torcher's Mask or similar gear. Be careful if you do this with a piece of equipment that lowers an attribute, since negative effects will stack as well (for instance, Button's Wig will lower Perception).

This is probably most useful when a follower equips a single piece of equipment that increases Luck (Lucky Shades, Ranger Battle Armor, Three Dog's Head Wrap) and applied until they reach Luck 10 which gives them a 10% Critical Chance. Doing it further is pointless, since Luck will not provide bonuses beyond 10 points, thus capping Critical Chance will cap at 10%.

Another nice combination is to apply the trick after equipping the follower with Poplar's Hood in combination with Enclave Power Armor and Lucky Shades. This will maximize the follower's Strength and keep Agility untouched (since the Agility loss from the Power Armor is negated by the Agility gain from the hood). The follower will also maximize his or her critical chance from the added Luck from the glasses. This makes for a really strong melee character, perfect for Clover, as long as you don't mind her looking ridiculous.

On the PC version of the game, to see if this actually works, you can open the console and target the follower: for example, to target Charon. Look at the follower's Wiki article to find their exact id number. After you've targeted the follower, you can use the command to make queries about their skills and attributes (,, ,  etc.)

Multiple Temporary Companion Exploit
Including Dogmeat and a permanent follower, it is possible to have a maximum of ten people following you without running into massive errors. Red, Shorty, Sticky, Sydney, Cherry, Initiate Pek, Paladin Hoss, and Paladin Hoss's anonymous co-paladin can all follow you around Falls Church area after rescuing Initiate Pek. However, after five game days, Cherry will return to Dukov's Place, and it's best to directly or indirectly kill Paladin Hoss, Initiate Pek, and their tag-along Brotherhood Paladin before leaving Falls Church, or you'll encounter some interesting game issues (360+ps3 unpatched). Because of this, the easiest sustainable number of followers is actually 6: Dogmeat, the permanent follower, Sydney, and the 3 Big Towners. This is the largest known following attainable resorting to game exploits, not glitches or coding errors.

Multiple Permanent Companion Glitches

 * Be aware that having more companions will increase the processing load on your system. You may experience low frame-rates, stuttering, freezing, graphic glitches, corrupt save games, (and most likely) system instability.
 * You might also experience euphoria when 12 people with Plasma Rifles mow down an Albino Radscorpion you didn't even know was there. It's a real mixed bag.

The following are possible in every version and patch level of the game.

1) Dogmeat has a reserved companion slot, meaning you will be able to get him no matter if you already have a companion. However, his death frees that slot. By killing him you'll be able to get two companions.

2) When you first meet Star Paladin Cross, she will join you initially (the first time you meet her) as long as you have good karma, regardless if you already have Dogmeat or other followers.
 * NOTE: In the conversation, you will come to a point where you have 2 conversation options, you must pick the second of the two :
 * "I want you to come with me."
 * "I don't suppose I could stop you."

3) When you meet Fawkes in the entrance of Raven Rock, he'll initially join you even if you have other followers. However, you will need to act quickly. Save immediately as you walk out of the large metal door of Raven Rock, before doing this. Before he speaks to you as you exit Raven Rock, you'll need to fast travel away from the location, pickup all other companions and then fast travel back. Fawkes may attempt to follow the Enclave soldiers that run away, and dissapear (or be very hard to find), forcing you to reload and try again.

4) Clover and Sergeant RL-3 can be acquired initially, even if you already have a follower, by abusing the "fire/rehire" glitch. This consists of firing your current companion, hiring Clover/Sergeant RL-3 and rehiring your previous companion before the recently 'bought' one starts conversation with you.

 Unlimited Companions (Broken Steel only)  (Confirmed on PS3 & Xbox360)


 * If you have the Broken Steel DLC you can use the Puppies! perk (requires level 22) to get every companion without much hassle. Just keep killing the new Dogmeat puppy and hire companions in their slot.

1) Get Dogmeat.

2) Get another follower to fill your companion slot.

3) Kill Dogmeat in the same area as the next companion you want to hire (you can't enter and load into a place or the new puppy will spawn). An easy way to kill Dogmeat is to tell him to go to Vault 101, and then pickpocket a live grenade onto him as he walks away.

4) Hire the companion, he or she will fill the open slot.

5) Enter a room or area other than Vault 101, and get the message that Dogmeat's puppy is waiting for you. Then pick up the puppy, he has created a new companion slot.

6) Repeat steps 3-5 until you have every possible follower.
 * By use of this glitch it is possible to have a lot of followers both before and after the events of Finding the Garden of Eden and The American Dream. This also allows you to complete the Fallout 3 add-ons without fear of breaking your follower glitches (keep in mind, however, that you will have to redo the entire setup, but this glitch never breaks, so feel free). This glitch makes the Puppies! perk one of the most useful perks in the game.
 * Dogmeat's puppy may spawn at Vault 101 and act frozen while remaining interactive via the usual talk prompts. If you order the puppy to follow you, it will be unable to do so. Tell Dogmeat's puppy to go wait at Vault 101, then "rehire" him a second time and he should be able to follow normally.
 * Killing your dog will occasionally get people around you to become hostile, so carry around Stealth Boys just in case before all hell breaks loose. Reverse-pocketing a grenade usually prevents this issue.

 Unlimited Companions (All platforms)  (Confirmed on PS3 & Xbox360)
 * With this glitch, you can get as many companions as you want, how many times you want. This means you can do this glitch prior to Raven Rock, then after it, without a problem. It is rather slow, so patience is necessary.

1) Hire Sergeant RL-3.

2) Go to the companion you want to hire, and tell Sergeant RL-3 to wait. Then talk to him again, and choose the second option("not just yet, I want to talk about something"). Then, fire him, wait for him to leave the room, and hire the other companion.

3) Wait 7-8 days, on an inside location (being outside voids this, for some reason). You should receive a "Sergeant RL-3 has returned to Canterbury Commons" message. This opens a companion slot.

4) Go hire him again.

5) Repeat steps 2-4 until you have all companions.

Tested and still works post-patch.
 * NOTE: As RL-3 requires neutral Karma, you may need more or less karma to acquire other followers. A quick way to lower karma is to hack a computer multiple times. A quick way to raise karma is by donating to Confessor Cromwell or by giving away purified water.

 Unlimited Companions (PC version only) 


 * Using the console you are able to hire ALL companions that meet your karma requirements. You will need Dogmeat to do this, because when you first meet Dogmeat there isn't a check for a free companion slot. If you then kill Dogmeat there will be a free slot, which can be used for another companion. Using console you have to resurrect Dogmeat, resetquest 943ed which will reset Dogmeat's dialogue, then hire Dogmeat, kill Dogmeat, and now you have another free companion slot. You can do this as many times as you need.

1. Open the console by hitting tilde key "~"

2. Kill Dogmeat: click on Dogmeat or type "prid 6a775", hit enter, then type "kill" exit console and hire desired humanoid companion or Sergeant RL-3.

3.* Resurrect Dogmeat: type "prid 6a775", hit enter, then type "resurrect" hit enter, type "resetquest 943ed" and hit enter, exit console and hire Dogmeat
 * NOTE: This is not possible if Dogmeat is immortal (setessential command). After you killed him he will fall unconscious and you aren't able to hire ANY other companion. After a while he will stand up and live again.
 * (to fix this just type ~ : setessential &lt;id&gt; 0 : enter)

 6 Companions (including Dogmeat alive)
 * To get 6 companions, you must not have used any fire/rehire glitch prior from your escape from Raven Rock.

1) When you escape from Raven Rock, you will be in a short tunnel, just before reaching the hatch, you will get the "You have found Raven Rock" message. Don't move any further, just stay inside the tunnel. This will also allow you to re-enter Raven Rock. You will see 3-4 hostiles and 1 friendly in your radar. The friendly who is fighting the 3-4 enclave soldiers is Fawkes and is here to rescue you. WAIT for him to kill all hostiles. He will then walk towards you or stop moving. Fast travel to Underworld and hire Charon. Because you will need to change your karma back and forth, Charon is easiest to work with since he has no karma restriction.

2) Get positive Karma and Fast travel back to Raven Rock. Fawkes will run up and initiate dialog. Let him join you. You might want to double check that the Raven Rock hatch is still open and that no invisible barrier is blocking you from going into the short tunnel and using the entrance door to Raven Rock.

3) Get karma to evil, go to Eulogy in Paradise Falls. Fire Charon, quickly talk to Eulogy and buy Clover. Before Clover initiates dialog with you, rehire Charon. Clover will join you now. Since you are evil now, you might want to fire either Fawkes or Clover and hire Jericho. Depends on whether you want a more powerful party or a party that can all wear power armor. Do not fire more than 1 companion at any time, or you will permanently lose 1 companion slot.

4) Get karma to neutral, go to Tinker Joe outside Robco building. Fire Charon, quickly talk to Tinker Joe and buy Sergeant RL-3. Before the Sergeant initiates dialog with you, rehire Charon. Same choice, you can keep Sergeant RL3 or hire Butch if you have already revisted Vault 101.

5) Get karma to good, go to Star Paladin Cross in the Citadel. She'll tell you that Elder Lyons is looking for you and won't say anything else. Just look for elder Lyons and let the cutscence play out. When Sarah asks if you are ready, tell her you need a minute. Now look for Cross again and speak with her. Select the lines that talks about your dad. When you reach the part where you can ask her to join you or say "I don't suppose I can stop you", select the latter. She will then ask to join you out of her own accord, now you can accept. If you had asked her to join you instead of the other way around, you will get a "Only 1 follower allowed" message.

6) Go get Dogmeat to join you. This can be done at anytime since he ignores the follower limit. However, he does create 1 if you kill him. So if you really want to, you can kill Dogmeat and get 1 of the remaining 2 companions (Butch or Jericho) in your party.
