WHERE & HOW TO FARM
Unlock Borderlands 4 endgame activities
Post-campaign mission list and map in the base game; each endgame system has its own introduction or access check.
Before you go
- Complete the main story campaign.
- Open the postgame mission list and accept available endgame introductions.
- Bring a campaign-ready build for the encounters those missions require.
Farming steps
- After the credits, open the mission list and note which postgame introductions are available.
- Complete the Ultimate Vault Hunter introduction when offered, then check the UVH challenge or mode access in-game.
- Complete the Firmware introduction to access gear Firmware transfer features.
- Complete Maurice’s Bounty introduction and verify access to Maurice’s Black Market.
- Complete the Big Encore introduction and check the boss rematch machine for its available options.
- Complete the Wildcard Missions introduction and confirm the weekly activity appears on the ECHO map.
- Choose a newly available activity that matches your current gear or progression goal.
- Treat each introduction as its own unlock; verify the feature in its menu or at its machine after finishing.
- Firmware transfer destroys the donor item and only works between gear of the same type, so inspect both pieces first.
Repeat, collect and use
The introduction missions are one-time progression. Some unlocked activities repeat, and weekly activities rotate; check their current in-game availability before planning a run.
Common mistakes
- Assuming credits alone make every endgame feature available: check for the relevant introduction and verify access.
- Treating the four feature introductions as one guaranteed sequence: complete the missions actually offered in your postgame list.
- Transferring Firmware without checking the donor: confirm gear type and accept that the donor is destroyed.
When to stop or switch
Stop the unlock checklist when the systems you intend to use are available in-game; then move to the matching activity or progression challenge.
