Borderlands 4 Co-Op Guide
Borderlands 4 supports up to 4-player co-op on Kairos with cross-play when enabled. Host the farm region you need, mix tank/control/DPS hunters, and share SHIFT-linked keys per account.
Invite from the Social menu. Cross-play must be on for mixed PC/console parties — see the cross-platform guide.
Loot is mostly per-player; rare shared world drops still respect each hunter's inventory.
Recommended mix: Amon or Harlowe for bunker safety, Vex or Rafa for boss DPS, optional C4SH or Loveless if DLC is owned.
Digirunners scale poorly if the host lags — prefer the most stable connection as host for Terminus Range jumps.
Golden Keys and SHIFT rewards are account-bound; each player redeems their own codes.
