About SDU Tokens
RespawnXP Borderlands 4 SDU Tokens — capacity-upgrade currency dropped on your Vault Hunter through a quick SHiFT co-op lobby. SDU lines are the least glamorous and most painful grind in any Borderlands game: backpack space, bank slots, and ammo reserves all want feeding before the endgame loot economy stops hurting. Pick 1,000, 5,000, or 9,999 (Max).
- Three tiers: 1,000, 5,000, or 9,999 (Max) SDU Tokens dropped on your character.
- The 9,999 tier maxes every SDU line: Backpack, bank, and ammo capacity — with room to spare.
- Picked up in minutes: Drops land at the spawn point in our lobby.
- Cross-platform via SHiFT — PC, PSN, and Xbox.
