“Characters that are part of your team are highlighted green in combat instead of red, if you have this Perk. Red highlighted characters may still be non-hostile towards you.”— in-game description, Fallout
With this perk, companions and allies (like members of a caravan while escorting a caravan for example) are highlighted green in combat instead of red, saving you the confusion of friends shooting other friends by mistake.
- This perk has no game mechanics effects, and just changes the highlight color of allied NPCs.
- This perk is misnamed "Friend-or-Foe" system.
- Green highlighting is the default setting in Fallout 2 and Fallout Tactics, making this perk obsolete.
