Crackling with mysterious power and a steep price tag, energy crystals in REPO are more than just shiny collectibles-they’re the lifeline that keeps your weapons firing and your gadgets humming deep into the game’s most dangerous runs. Whether you’re desperate to recharge a drained drone or reload your last line of defense, mastering these elusive yellow crystals could mean the difference between a triumphant escape and a truck full of deadweight.
What are energy crystals used for in REPO?
Energy crystals in REPO are essential items used to recharge and restore the functionality of your weapons, tools, and electronic devices. As you progress through the game, many items-such as guns, melee weapons, drones, and detectors-will lose power or ammunition after repeated use. Instead of buying costly replacements, you can use energy crystals to refill these items at the energy machine located in your truck, saving significant money and resources. This makes energy crystals especially valuable in the mid to late stages of the game, as they allow you to keep your gear operational for longer runs and tougher challenges.
You need energy crystals to recharge or reload your weapons and tools. Weapons like the baseball bat and frying pan have a certain number of times they can hit things before they need to be recharged and guns will run out of ammo after use. Even items like drones and detectors will run out of juice, so you’re going to want to recharge them rather than just buying new ones.
That said, this is more of a mid- to endgame item, so you don’t need to worry too much about buying energy crystals within the first few runs. Focus on building up your stamina and strength first.
How to use energy crystals in REPO
Energy Crystals in REPO are used to recharge your weapons and tools, ensuring they remain functional throughout your runs. After purchasing Energy Crystals from the Service Station shop between levels, they are automatically placed in your truck’s energy charging station. To use them, simply place any depleted weapon or device-such as guns, drones, or detectors-into the energy container inside your truck. The item will recharge after a few seconds, allowing you to reuse it without having to buy replacements. Since Energy Crystals are consumed during this process and can be expensive, it’s wise to stock up as you progress, especially if you rely heavily on energy-dependent equipment for tougher missions.
Once you buy the energy crystals, they’ll automatically be loaded into your truck in the energy machine (full disclosure: I do not know what the machine is called). You can hold up to six crystals and they get exponentially more expensive the more you buy. Your machine will start with one crystal and a bit of juice.
To recharge your weapon or tool, just put it in the square-shaped bin next to the machine. You can see how much juice your recharge machine has by looking at the yellow bar on the right side. You’ll see it go down as your item recharges.
One crystal can fully recharge any item, so you’ll want to make sure the item you’re recharging is completely empty before dumping it in, to make the most of the crystal.
How can I maximize the use of energy crystals in late-game REPO
Maximizing Energy Crystal Use in Late-Game REPO
Prioritize Critical Tools and Weapons
-
In late-game REPO, energy crystals become essential for keeping your most powerful weapons and gadgets operational. Focus on recharging high-impact items like firearms (especially shotguns and guns with limited shots), drones, and essential detectors first, as these are crucial for survival against tougher enemies and completing objectives efficiently.
Recharge Only When Nearly Depleted
-
To get the most out of each crystal, only recharge items when they are almost completely drained. Since each crystal has a limited number of charges, topping up half-used items wastes potential energy and increases your running costs.
Leverage the Recharge Drone for Field Operations
-
If you’re far from your truck, use the Recharge Drone to top off gear and revive drones on the go. This minimizes downtime and prevents risky backtracking, but remember the drone itself consumes crystals, so plan your usage and crystal allocation accordingly.
Manage Inventory and Shop Smart
-
Energy crystals are only available for purchase at service stations between levels, and their cost increases as you progress. Buy in bulk early if you can afford it, and always keep a reserve for emergencies. Hoarding a few extra crystals ensures you’re not left powerless during critical moments.
Coordinate with Your Team
-
In multiplayer runs, share the responsibility for purchasing and using crystals. Pool resources to keep everyone’s key equipment charged, especially before boss encounters or challenging sections.
Summary Table: Late-Game Energy Crystal Strategy
| Tip | Why It Matters |
|---|---|
| Recharge only critical tools | Maximizes survival and efficiency |
| Wait until items are nearly empty | Prevents waste, saves crystals |
| Use Recharge Drone wisely | Keeps gear running in the field, saves time |
| Buy in advance, hoard extras | Avoids price hikes, prevents shortages |
| Team coordination | Ensures all players stay equipped and effective |
By following these strategies, you’ll stretch every energy crystal to its limit and maintain your combat edge deep into REPO’s toughest challenges.
What are the most cost-effective ways to use energy crystals late-game in REPO
Most Cost-Effective Ways to Use Energy Crystals Late-Game in REPO
1. Recharge Expensive and Essential Gear First
-
Use energy crystals primarily to recharge high-value items like guns, drones, and advanced detectors. Recharging these items is far cheaper than buying replacements, especially since top-tier weapons and drones can cost up to $50,000, while a crystal costs $7,000-$9,000.
2. Avoid Buying Duplicate Equipment
-
Instead of purchasing multiple copies of the same weapon or tool, invest in energy crystals to keep your existing gear operational. This approach significantly reduces your long-term expenses and inventory clutter.
3. Wait Until Items Are Nearly Depleted
-
Only recharge items when their energy is almost fully drained. This ensures you get the maximum value out of each crystal, as partial recharges waste potential energy.
4. Pool Resources and Plan as a Team
-
In multiplayer, coordinate crystal purchases and prioritize recharging items that benefit the entire group, such as shared drones or detectors. This prevents unnecessary spending and ensures everyone’s gear stays functional.
5. Buy in Bulk Before Price Increases
-
Energy crystal prices rise as you progress. Stock up early, especially after level 3 when you start acquiring more energy-dependent gear, to avoid paying inflated prices later in the game.
6. Use the Truck’s Recharge Station Efficiently
-
Always use the recharge station in the back of your truck between runs. Drop depleted items in the recharge bin to quickly restore them for the next mission, rather than scrambling for replacements mid-run.
Summary Table: Cost-Effective Crystal Use
| Tip | Why It Saves Money |
|---|---|
| Recharge expensive gear, not cheap | Avoids high replacement costs |
| Don’t buy duplicates | Reduces unnecessary spending |
| Recharge only when nearly empty | Maximizes each crystal’s value |
| Team planning | Prevents redundant purchases |
| Buy early, avoid late-game price hikes | Locks in lower prices |
By following these strategies, you’ll stretch every energy crystal further and keep your late-game REPO runs both efficient and profitable.
