These encounters occur anywhere and typically involve two factions or enemy types that have particularly strained or nonexistent diplomatic relations with one another.
Animosity Encounters
| Encounter | Notes |
|---|---|
| Encounter | Notes |
| Super Mutants versus Ghouls | Sit back and watch infected bony fingernails scrape against overly large green hides. |
| Super Mutants versus Scavengers | A one-sided battle, with Super Mutants already victorious and moving back to a nearby stronghold. |
| Raiders versus Scavengers | Come for the fighting. Stay for the loot one of the Scavengers had collected. |
| Dogs versus Farmers | Only the dogs are hostile. |
| Scavengers versus Robots | Both groups are hostile if you barge in uninvited. |
| Minutemen versus [Other Faction] | Once you ally with the Minutemen, you may encounter a group of them defending a settlement from Brotherhood of Steel soldiers, Institute synths (who may use relaying to ambush), or one or more Institute Coursers. Help out your chosen faction. You must have been kicked out of the faction that is attacking. |
| Brotherhood of Steel versus [Other Faction] | Once you ally with the Brotherhood of Steel, you may encounter a group of them defending a settlement from Minutemen, Institute synths (who may use relaying to ambush), or one or more Institute Coursers. Help out your chosen faction. You must have been kicked out of the Institute if they are attacking. |
| Minutemen versus [enemy] | Once you ally with the Minutemen, expect to see them defending random locations in the Commonwealth. These small outposts may be attacked by Raiders or Gunners; lend them a hand if you can. |
| Brotherhood of Steel versus [Enemy] | Once you ally with the Brotherhood of Steel, expect to see them at a random location, attacked by Feral Ghouls or Super Mutants. |
| Institute Relay Ambush | If you’ve been kicked out of the Institute and the faction is still active, you may be attacked by teleporting synths as you near a location. |
| Vicious Dogs versus Bloodbugs | A human corpse serves as a rag doll being torn between dogs and bugs, both parties wishing to devour it. |
| Feral Ghouls versus Raiders | A group of wandering corpses do battle against the idiotic wastrels of the Commonwealth. |
| Active Sniper | Some lunatic with a sniper rifle enjoys shooting up the location you’re entering. |
| Ricky Dalton and the Raiders | Once Railroad Quest: Tradecraft is complete, you may see him fighting off Raiders. |
| Gunners versus Children of the Atom | Feel free to watch both these enemy factions make (lightly irradiated) mincemeat of each other. |
| Gunners versus Behemoth or Mirelurk Queen | A trio of Gunners are making impressive inroads against one of the Commonwealth’s true giants. |
