Deathloop How To Use Residuum

Deathloop is a stylish, time-twisting first-person shooter where players step into the shoes of Colt, an assassin stuck in a mysterious loop on the island of Blackreef. One of the key mechanics introduced as you progress through the game is the concept of Residuum. This glowing, ethereal substance is essential if you want to break the loop and keep your most powerful gear. Understanding how to use Residuum effectively can make a massive difference in your playthrough. With a little strategy and planning, players can build the perfect arsenal to survive each cycle.

What Is Residuum?

The Core of Progression in Deathloop

Residuum is an energy source that allows you to infuse weapons, Slabs, and gear so they carry over from one loop to the next. At the beginning of the game, Colt loses all gear when a loop resets. However, once the Residuum mechanic is unlocked, players gain the ability to stabilize their favorite loadouts, preserving progress and increasing efficiency in future loops.

You can think of Residuum as a currency of permanence in a world built on repetition. Without it, everything resets. With it, you can shape the tools you want to rely on long-term.

How to Collect Residuum

Sources of Residuum in Blackreef

Residuum is not something you find in unlimited supply. It is hidden across the game’s four districts and can also be extracted from special sources. Here’s how you can gather Residuum throughout each loop:

  • Glowing Objects: Some objects in the environment shimmer with a strange glow. Approach and absorb them by holding the appropriate button prompt. These are usually static sources scattered around the map.
  • Killed Visionaries: Defeating a Visionary (the key targets in the game) grants a large amount of Residuum. Visionaries are also your main source for Slabs, which are powerful abilities.
  • Recycling Weapons and Trinkets: You can sacrifice unwanted weapons and gear for Residuum in the loadout menu. This is particularly useful when your inventory is full or when duplicates appear.

Collecting Residuum is often a matter of balancing exploration with combat. Smart players will seek out glowing items while also hunting down Visionaries during key windows of opportunity.

How to Infuse Gear

Understanding Infusion

Once you’ve obtained Residuum, the next step is using it to infuse your items. Infusing means permanently keeping an item even after the loop resets. This allows you to build a consistent loadout for future runs, drastically improving your effectiveness.

To infuse gear:

  • Open theLoadout Menubetween missions.
  • Hover over the item you want to keep this could be a weapon, a Slab, or a Trinket.
  • Hold the infusion button (usually indicated on-screen) to spend Residuum and lock in the item.

Once infused, the item will remain in your inventory at the start of every loop. This is vital for developing your personal playstyle, whether you prefer stealth, chaos, or a combination of both.

What Should You Infuse First?

Choosing the Right Items to Keep

Not all gear is worth keeping, especially when Residuum is limited. Prioritizing what to infuse can make a big difference in your long-term success. Consider the following when deciding:

  • Slabs and Slab Upgrades: Abilities like Blink, Nexus, and Havoc can completely change the way you play. These should be a top priority for infusion.
  • Legendary Weapons: Unique, named weapons have special perks that regular guns do not. Infusing these ensures you always have powerful tools at your disposal.
  • Rare Trinkets: Purple or gold-tier Trinkets can provide significant stat boosts or useful modifiers. Infuse the ones that match your playstyle.

Early in the game, you’ll be tempted to keep everything. But as your Residuum stash grows, you’ll be able to afford more upgrades and make better long-term decisions.

Managing Residuum Wisely

Don’t Waste This Resource

Residuum isn’t unlimited, and wasting it can set you back. Consider these tips to manage it effectively:

  • Always check your inventory: Before ending a day or loop, review your items and infuse anything essential that you can afford.
  • Don’t hoard junk: Sacrifice gear you don’t use. Convert it to Residuum rather than keeping cluttered options.
  • Use the full day: Deathloop’s day cycle includes morning, noon, afternoon, and evening. Make the most of each segment to gather Residuum and hunt Visionaries.

The game rewards careful planning. Try to maximize your gains each day so that by evening, you’re ready to lock in powerful new tools.

What Happens If You Die?

Protecting Your Residuum

One of the biggest concerns players have is what happens to collected Residuum when they die. If you die three times within the same time segment, you lose all unspent Residuum. To avoid this:

  • Spend it before moving to a new district or time period.
  • Don’t get greedy.Sometimes it’s smarter to leave with what you’ve gathered instead of pushing your luck.
  • Use Colt’s Reprise ability(a form of extra lives) wisely to recover from fatal mistakes without losing everything.

If you die once or twice, your Residuum is dropped at your corpse and can be recovered. But die a third time, and it’s gone for good.

Tips for Residuum Farming

Maximizing Each Loop

To build up a strong reserve of Residuum, consider these farming strategies:

  • Kill multiple Visionaries in one day.Their Residuum drops are the most valuable.
  • Explore every area.Even less dangerous districts often contain glowing objects to harvest.
  • Sacrifice lower-tier gear after each successful mission.Don’t carry extras you won’t use.
  • Replay Visionary encounters with a plan.Learn their habits and spawn points for quick execution.

With the right routine, you’ll never find yourself short on Residuum again. This makes your future loops easier, faster, and more customized to your preferred combat style.

Building a Perfect Loadout

Crafting Your Playstyle

As you gather more Residuum and infuse better gear, you’ll start to shape a perfect build. Whether you enjoy stealth, aggression, or supernatural powers, Residuum enables the freedom to experiment. Don’t be afraid to test new Slabs and weapons you can always recycle them later if they don’t suit you.

A consistent, well-infused loadout not only increases your chances of beating the game but also enhances the enjoyment of each run. You’ll move through districts faster, eliminate targets with precision, and react better to surprises.

Learning how to use Residuum in Deathloop is key to mastering the game’s core loop mechanic. It transforms temporary progress into permanent advancement, allowing you to shape the perfect assassin toolkit. From collecting it in the field to choosing what to infuse and when to spend it, every decision matters. With smart Residuum management, each loop becomes not just a repeat, but a step forward. Whether you’re experimenting with new powers or chasing perfection, mastering Residuum ensures Colt gets closer to breaking the loop on your own terms.
