Borderlands 4 Guides
Answer-first guides for cross-play, Golden Keys, vault fragments, beginners, and endgame loops.
Is Borderlands 4 Cross Platform?
Yes. Borderlands 4 supports cross-platform co-op across PC, PlayStation 5, Xbox Series X|S, and Nintendo Switch 2 when cross-play is turned on in party settings.
Borderlands 4 Golden Keys
Golden Keys open the golden chest in unlocked safehouses for randomized gear. Most keys come from active SHIFT codes; some editions grant bonus keys.
Vault Key Fragments
Vault Key Fragments are consumables that unlock higher-tier Vault runs. Collect them from story beats, bunkers, and world activities, then spend them at Vault doors.
Borderlands 4 Beginner Tips
Pick one base Vault Hunter, unlock Digirunners and safehouses early, redeem SHIFT golden keys at mid levels, and follow manufacturer synergies instead of equipping every legendary you see.
Borderlands 4 Endgame Guide
Endgame on Kairos is boss targets (Bloomreaper, Bio-Bulkhead), Order bunker chest loops, Maurice weekly legendaries, and high-tier Vaults spent with key fragments.
