Discovering the Path to Enhanced Capabilities: Methods for Gaining SDU Tokens in Borderlands 4

In Borderlands 4, SDU tokens are exclusively obtained through the discovery of collectibles and the completion of various challenges across the game world. While some tasks involve straightforward interactions like activating a shrine or a vault symbol, others demand navigating intricate dungeons culminating in boss battles. It's important to note that the difficulty setting of the game does not influence the number of tokens rewarded for these activities. Below is a comprehensive list of all collectible types that yield SDU tokens.

Strategic Positioning: Unlocking Safehouses and Silos for Substantial Rewards

Throughout the map, numerous Safehouses and Silos serve as crucial fast travel points. Activating each of these locations provides a generous reward of 40 SDU tokens. Given the relative simplicity of unlocking them, prioritizing the discovery and activation of these points of interest is an excellent strategy for quickly accumulating a significant amount of SDU tokens.

Unraveling Ancient Mysteries: Solving Evocarium Puzzles for Valuable Tokens

To successfully complete an Evocarium puzzle, you must first interact with its central mechanism, which will then highlight three distinct locations. Your next step is to explore these marked areas to find three luminous orbs. Upon collecting all three, you will be rewarded with 15 SDU tokens.

Uncovering Hidden Secrets: Interacting with Vault Symbols for Quick Gains

As you traverse the landscapes of Kairos, keep an eye out for glowing Vault symbols etched onto various surfaces. Simply interacting with these symbols will immediately grant you five SDU tokens, offering a small but consistent stream of upgrades.

Retrieving Lost Technology: Recovering Capsules for Arsenal Expansion

This objective involves locating a lost capsule and returning it to a designated drop-off point, typically situated within a nearby base or Safehouse. Successful delivery not only earns you 15 SDU tokens but also dispenses a selection of weaponry from the retrieval machine.

Activating Ancient Artifacts: Engaging with Auger Shrines for Rewards

Auger shrines are unique points of interest that, when interacted with, reveal a hidden shrine from within a machine. To claim your rewards, you must perform a melee attack on the exposed purple shrine. This action will provide you with 10 SDU tokens and additional weapon drops.

Silencing Disinformation: Dismantling Propaganda Speakers for Tokens

Marked by a speaker icon on your map, propaganda activities present a tower-defense-style challenge. Your mission is to hack the structure while fending off waves of incoming enemies. Successfully defending the hack until the progress bar reaches 100% will reward you with 20 SDU tokens.

Cracking Open Riches: Accessing Electi Safes for Hidden Treasures

These small, neglected safes are found in specific locations indicated on your map and can yield 10 SDU tokens. All that is required is to locate the safe and, quite simply, deliver a forceful kick to open it.

Navigating Secure Facilities: Conquering Order Bunkers for Major Payoffs

Order bunkers are essentially miniature dungeons that require players to clear rooms filled with adversaries. Progression often involves additional challenges, such as locating and installing batteries to unlock sealed doors. A boss awaits at the conclusion of each bunker. Successfully completing a bunker grants a substantial reward of 40 SDU tokens.

Venturing into the Depths: Exploring Abandoned Auger Mines for Valuable Tokens

These deserted mines are comparable to bunkers in structure and also award 40 SDU tokens upon completion. However, Auger mines introduce different types of enemies, such as manglers, and incorporate environmental hazards like pools of corrosive poison that must be avoided.

Dismantling Enemy Operations: Clearing Ripper Drill Sites for Rewards

For a more direct challenge, target the Ripper drill sites. These are Ripper encampments where the objective is to eliminate standard enemies until a mini-boss emerges. Defeating the mini-boss will not only yield valuable loot but also award you with 40 SDU tokens.

Conquering Colossal Remains: Activating Ancient Crawlers for Ultimate Rewards

Massive, derelict vehicles known as Ancient Crawlers are scattered across Kairos. By reaching the top of these behemoths, you can power up their systems to acquire their unique vehicle kits. This endeavor will require you to confront numerous enemies before you can access the summit of the Ancient Crawler. However, perseverance will be rewarded with 40 SDU tokens upon successful completion.
