Deathloop: Powers & weapons - how to keep? Deathloop guide, walkthrough

Last update: 23 September 2021

On this page of our guide to Deathloop you'll find info regarding keeping Colt's weapons and powers for usage during subsequent Loops, which helps you progress in the game. We've listed a walkthrough of the Ubiquity arsenal lead which is tied to this mechanic. Thanks to this lead you'll learn about Residuum and unlock infusing gear.

Basic info

1. Note that in Deathloop, each death of Colt reset of the time and the character returns to the starting point on the beach. In that case, you will need to re-visit places where the Visionaries are to eliminate them again.
2. Restarting the cycle causes the loss of previously acquired powers and weapons - you have to start collecting new abilities and items all over again.
3. The game features a resource called Residuum, which allows you to keep some of your progress. By using Residuum you may, for example, keep the chosen powers or weapons in order to keep using them even after the Loop restarts. This can make it much easier for you to progress in the next time loop. We've described how to unlock collecting Residuum below.

The Ubiquity Arsenal Lead

To gain the possibility of collecting Residuum and permanently purchasing weapons and hear, you must first complete the Arsenal Lead (mission) Ubiquity. Fortunately, you can't miss it. It's received automatically after finishing Colt's prologue we've described on a separate page of the walkthrough, that is, after finding documents stashed in a safe in the protagonist's apartment. Doing so equals progressing to the main part of the game, with the aforementioned lead appearing in your journal.

This mission tasks you with finding the research conducted by Doctor Wenije, one of the Visionaries (bosses). To do so, you must return to the tunnels and, from there, visit The Complex during the afternoon.

Your objective is reaching the large, multi-storey building housing Wenije's Laboratory.

As soon as you get to the lab, you will discover that there is a large number of Wenjie instead of a single opponent. You must start gradually eliminating them, until you dispatch all the "copies" and defeat the Visionary.

Examining the lab itself is equally as important. First of all, approach the board shown in the picture and notes attached to it. (To Reap What You Sow; Unknown Unknowns). You will learn about the Residuum.

Continue to fight remaining Wenije copies until you manage to deal with all of them.

Go back to the board and find the Portable Harvester nearby.

Get the device to the last defeated Wenjie, and use it on her suck up the remains and get Residuum.

With the device is filled, you have to reach a infusor in the laboratory. Insert the harvester into the side slot.

Now you just need to activate the experiment - you need to enter the large chamber and use the Hackamajig to remotely activate the device (look towards the button with your gadget out to locate the hacking place).

Colt will die at that moment (don't worry, this is planned), and after being reborn on the beach, you will be able to collect Residuum in the game world.

Collecting and spending Residuum - description of this new mechanic

You can collect Residuum in two different ways:

1) Finding shiny objects in the game world - Once you get close to such an object you can hold down the interact button to "suck out" the Residuum.

2) Eliminating Visionaries (including Julianna) - Each defeated Visionary-boss will turn into a very big Residuum deposit.

You can spend Residuum inside the tunnels visited between main quests, in the preparations menu before each of your trips. The two most important options are:

1) Infuse - You can use this action on obtained weapons, weapon upgrades, Trinkets, Slabs (powers), and Slab upgrades. This is the only way to avoid losing found objects as the Loop ends. Once you "purchase" something by infusing it, this item will remain in your inventory permanently (unless you decide to sacrifice it, as described below).

2) Sacrifice - This action allows you to destroy an object (a weapon, a slab, a trinket, etc.) in return for some residuum. You should decide to do so if you urgently need Residuum to infuse more important items, if you know that an item won't be of any use to you, or if you already own a similar or identical item and don't need a spare.

It's very important to spend the gathered Residuum during the currently played Loop, that is, before the day ends. Otherwise unused Residuum will be lost once the next Loop starts.

The game, fortunately, allows you to Infuse and Sacrifice items even after you return from the final location visited during the Evening. You'll be able to Infuse the items you want before you choose to move on to the next Loop / the next day.
