Bio-Boosters are scattered randomly across the maps in Deep Rock Galactic: Rogue Core, and some of them hide a hacking minigame that rewards you with class modifiers. The mechanic shows up early in a run, and if you've never seen it before, the interface can be a little disorienting. Here's exactly what you need to do to nail it every time.
What is a Bio-Booster hack?
Bio-Boosters are upgrade terminals you encounter during a run. Most of them offer standard upgrades, but certain ones give you the option to hack them. A successful hack rewards you with a class modifier, which you can choose from a small selection after completing the minigame. Class modifiers are currently the only reward available from these hacking terminals.

How to complete the hacking minigame
The hacking interface shows two wires: one blue and one red. Each wire has connection points at both ends, and you need to link them in sequence. The pattern is identical for both wires, so once you've done it once, the rest is muscle memory.
Step 1: Connect the blue wire nodes
Watch the screen until a node on the blue wire lights up. That's your target. Click when the correct node is highlighted. You need to connect both endpoints on the blue wire before moving forward.
Step 2: Hit the secondary node on the blue wire
After connecting both endpoints, a third node appears somewhere along the blue wire itself. Click when your cursor lands on that highlighted spot to finish the blue wire sequence.
Step 3: Repeat the process for the red wire
The red wire uses the same two-step process. Click when each endpoint is highlighted, then click the secondary node that appears along the wire.
What happens after a successful hack?
Once both wires are connected, the terminal unlocks and shows you a selection of class modifiers. Choose whichever one fits your build. These terminals don't drop anything else—no hidden loot, no surprise upgrades. Just the modifier selection.

Tips for hacking efficiently
- Clear enemies first. The timer is forgiving if you're focused, but a single bug swarm mid-hack will wreck your attempt.
- Watch for the highlight, not the cursor. The game tells you exactly when to click by lighting up the correct node. Don't try to guess ahead.
- Don't rush the first click. Missing a node resets that step and burns time you don't have.
- Pick modifiers that complement your class. The selection is random, but always lean toward upgrades that work with your current weapon loadout.
For more strategies across every class and upgrade system, the Deep Rock Galactic: Rogue Core strategy guides collection covers the full breadth of mechanics you'll want to understand before diving deeper into the roguelite loop. Rogue Core sits firmly in the action games space, and the Bio-Booster hack is one of the smaller systems that separates players who squeeze every advantage from those who walk past free class upgrades without a second thought.
