Fallout 3 exploits

Exploits are "holes" in the game programming which allow a player to do something which the developers did not intend, and alter the play balance in a way which cannot be rectified.

Exploit/Bug ==
 * It is possible to freeze your current amount of scrap metal through Protector Casdin (confirmed on 360 & PS3). This method can be done directly after leaving Vault 101. Saving after each step is highly suggested:


 * 1) First, an even number of scrap metal is needed. 16 is a recommended quantity.
 * 2) Give Casdin all scrap metal in your inventory. This batch is the X Value. Note! This value must be an even number (10, 12, 14 etc).
 * 3) Steal back the X Value scrap metal you gave Casdin.
 * 4) Give back all scrap metal except 2 for the best possible profit. This batch is the Y Value.
 * 5) Steal back the Y Value scrap metal from Casdin.
 * Now, attempt to steal anything from Casdin. If you do not get caught, reload the save and try again until he does catch you. Casdin will then proceed to take back his scrap metal, but will steal back both the X Value and the Y Value. For example, if you gave him 16 scrap metal, stole them back and then gave him 14 scrap metal, it will say that he removes 14 scrap metal and then 16 scrap metal.


 * This will glitch your scrap metal value so that you have a Z Value which is negative. It will appear as if you have no scrap metal at all in the inventory, but when you speak with Casdin, Winthrop or Walter you will still have the option of giving them scrap metal.
 * Following the example above, if you first gave him 16 scrap metal, stole them back and then gave him 14, you will have 14 invisible scrap metal in your inventory that can be given away to Walter, Casdin and Winthrop. Most importantly, this amount of invisible scrap metal is permanent, meaning it can be given away infinite times, as long as you do not pick up any additional scrap metal (which will reset the negative value back to normal).
 * Used early in the game with Walter, this glitch can launch a level 2 character to max level very quickly, netting over a hundred thousand caps in the process, depending on if you ask for payment for the scrap metal.
 * This glitch may not work for some players. At the final step, stealing one of Casdin's other items, for some users it will just cause him to attack the player and not take back any of the items. There is currently no known way to get around this, but it is known that starting a new character and performing the glitch straight out of Vault 101 will work.

Kill NPCs without consequences
Collision with many in-game objects such as swing objects, barrels and even tin cans can inflict damage upon collision with characters. This effect, combined with certain limitations and inaccuracies of the in-game physics engine can be exploited by the player character in order to cause the death of any non-essential NPC without karmic impact or inciting hostility within the allies of the target NPC or bystanders. The basic requirement for the exploit is access to a grabable object with potential to inflicting damage upon collision. Note that not all objects have this ability, for example a dropped Flamer cannot be used for this purpose, but rusted barrels found in many populated areas can. The principle of the exploit is simple but practical execution can be anything from quick & easy to time consuming & tedious depending on the NPC, his/hers location, availability of objects on the map cell, etc.

The procedure of the exploit is as follows:
 * Grab (press z) and place the object (barrel, eg.) next to and as close as possible to the intended victim.
 * Position yourself so that the object is between you and the victim.
 * Move/run towards the victim, consequently pushing the object at him/her. Keep trying to move toward the victim even when you are not moving anymore, causing the object to start "stutter" between you and the victim.
 * The victim will lose health upon the numerous collisions with the "stuttering" object.
 * Repeat until the victim dies.

Notes:
 * As the victim dies, none of the non-hostile NPCs will turn on the player character as the victim NPC was marked as getting killed by a collision and not by aggression from any character.
 * The object will often "launch" away at high velocity when pushed against the NPC, making retrieving the object tedious as the object can be propelled across considerable distances and elevations.
 * Noisy annoyances such as Confessor Cromwell, etc. can be easily disposed of via the exploit.

Companion exploits

 * Using these exploits while having multiple followers will make the game unstable.
 * 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.

Multiple Permanent Companions (all versions)
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, and you must pick the second of the two choices:
 * "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 disappear (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.

Equipment Effect Stacking
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 Companions
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.

Unlimited Companions (Broken Steel only)
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.( The problem is it takes FOREVER to kill him)

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.

(Confirmed on PS3 & Xbox360)

Unlimited Companions (All platforms)
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.


 * 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.

 (Confirmed on PS3 & Xbox360)

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.

Unlimited Companion Clones in the Game (PC Version Only)

 * To get an unlimited number of companion clones do the folowing:

1) Hire the companion you want to clone

2) Enter the code in the console: player.placeatme (enter base id of follower) 1 1

3) All done!
