When the monsters hit harder and your trusty Tranq Gun runs dry, there’s one thing you’ll be desperate for in REPO: Energy Crystals. These glowing yellow lifesavers are the secret sauce behind your survival and the key to keeping your gear in fighting shape.

Here’s everything you need to know about how to get Energy Crystals in REPO and how to use them wisely so you're not left swinging an empty Fry Pan.

What Are Energy Crystals?

Energy Crystals are a core resource in REPO, acting as the fuel, ammo, and repair juice for most of your weapons and gadgets. Whether you're patching up your Inflatable Hammer or recharging your Recharge Drone, these crystals are your go-to for keeping things powered.

Important: Energy Crystals are not the same as stamina upgrades for your Semibot. Those happen at the Service Station too, but Crystals are strictly for recharging weapons, tools, and tech.

How To Use Energy Crystals

Using Energy Crystals in REPO is super simple and mostly automatic.

1. Head to the truck’s recharging station. Look for the box with a lightning bolt symbol.
2. Drop your low-durability item (like the Tranq Gun, Inflatable Hammer, or any drained tool) into the glowing yellow box.
3. The station will consume energy from the crystals slotted into it and repair your gear.

Each crystal has limited charges, so choose carefully. Prioritize recharging your most critical tools first, nothing feels worse than running into a boss fight with a half-dead drone and no juice left in the tank.

Don’t Forget the Recharge Drone

Far from your truck? The Recharge Drone has your back. It's a mobile energy source that can top off your gear and revive other drones while you're out in the field. Just remember—it needs Energy Crystals to operate, which means keeping it powered still depends on your supply back at the truck.

Pro tip: Don’t be like the rest of us who stubbornly walk back to the truck every time something breaks. That’s how you lose runs.

How To Get More Energy Crystals

Energy Crystals aren’t pickups you’ll find lying around mid-mission, they’re bought at the Service Station between levels.

• Cost: Typically 7,000 to 15,000 credits per crystal
• Stock: Replenished each time you visit the Service Station

They’re consumable and non-refundable, meaning once a crystal is drained, it’s gone for good. Prices also go up as you progress, so it’s smart to start hoarding early. Even if you’re not using fancy weapons yet, future-you will thank you.

Final Tips

• Always check your crystal count before heading out.
• Balance what you recharge, sometimes a slightly busted Hammer can wait.
• Don’t burn through your stash recharging everything. Prioritize.
• Buy whenever you can afford to, these things only get pricier.

Whether you're bonking monsters with a cartoon mallet or stealthing around with your drone squad, Energy Crystals are what keep the wheels turning in REPO. Plan ahead, recharge smart, and don’t get caught empty-handed when things go sideways.
