Big Leagues is a perk in Fallout 4 and Fallout: The Roleplaying Game.

Fallout 4

Swing for the fences! If you design a bludgeoning or bladed method of bringing an end to your foes, this is the perk to take. Though difficult to battle against multiple enemies in the same space, close combat is much more impressive when your damage is increased. Check the Weapons chapter for more information on available melee weapons.Fallout 4 Vault Dweller's Survival Guide description

  • Upon getting a "grand slam" with the perk level at 5 a small animation appears and a short round of applause can be heard.
  • The chance to cripple with rank 5 of the perk is roughly 20% per swing.
  • On the 4th rank of the perk, the player character's melee attacks do damage to everything in front of them, that means also neutral units that are around the target, rendering the melee attacks dangerous to the Sole Survivor as it can turn neutral or friendlies against them.
  • Rank 4 of this perk can make it impossible to save Kent while using melee weapons in the Silver Shroud quest. Sinjin stands close enough to Kent that Big Leagues 4 will also kill Kent.
