All Ways To Get More SDU Tokens in Borderlands 4

In Borderlands 4, there are multiple methods to help you earn more SDU tokens. However, each of them is unique with its own requirements, rewards, characters, and more. Below are the detailed methods to help you collect SDU tokens:
- Safehouses and Silos: If you have spent some time in the game until now, you would have probably found many Safehouses and Silos. In addition to being a fast travel point on the map, they offer 40 SDU tokens for unlocking them. Since there are 14 Safehouses and 9 Silos, you can earn a total of 920 SDU.
- Evocarium Puzzles: When you find these puzzles in Kairos, interact with them to receive a quest to find three glowing orbs from three locations. After obtaining them, you will earn 15 SDU tokens.
- Vault Symbols: While exploring the vast area of Kairos, you will find glowing Vault symbols on the walls. Interact with them to earn 5 SDU tokens.
- Lost Capsules: Out of the various methods mentioned for farming SDU tokens, this activity is probably the easiest one. To collect tokens, find a lost capsule and deliver it to Safehouses. That way, you earn 15 tokens as a reward. There are a total of 20 capsules, yielding a maximum collection of 300.
- Interact with Auger Shrines: You can find 10 Auger Shrines in BL4 by interacting with some specific points of interest. Each purple shrine offers a chance to earn 10 SDU tokens in Borderlands 4.

- Propaganda Speakers: In Borderlands 4, you can spot Propaganda Speakers with the help of their markings on the map as a speaker icon. These are sort of mini-missions where you hack into the network and disable the speakers. That way, you can collect a total of 540 SDUs, 20 tokens for each speaker.
- Electi Safe: You can find a total of 10 safes, scattered across the Carcadia Burn and Dominion regions. Additionally, each safe has 10 tokens, which means you can get 100 SDU tokens from this method.
- Order Bunkers: These bunkers are areas filled with enemies and also include a boss. Keep progressing through the challenges of the dungeon, and after clearing the area of enemies, you get 40 SDUs. You can find five more such bunkers to collect even more tokens.
- Auger Mines: You can fight the enemies in the abandoned Auger mines to collect SDU tokens. Since there are a total of seven enemies there, and clearing each will provide you with 40 SDUs, you can get 280 tokens from these mines.
- Ripper Drill Sites: Once you arrive at the drill sites, you will encounter several Ripper enemies and a mini-boss, which appears after clearing out the regular soldiers. After defeating these enemies, you will receive 40 SDUs for each site. Additionally, there are six such areas, allowing you to collect a total of 240 tokens this way.
- Ancient Crawlers: In Kairos, you will often stumble across some abandoned giant vehicles. Climb to the top of them, and you can receive 40 SDUs for each crawler. Since there are 10 crawlers in BL4, you can earn 400 tokens. However, you have to deal with some enemies along the way to the top.
That was all about how to get more SDU tokens in Borderlands 4.
