Collecting your first fistful of Residuum automatically unlocks the ability to infuse items. In order to learn how to infuse your gear, you need to kill Dr Wenjie Evans - one of Blackreef's eight Visionaries - and loot the 10,000 Residuum from her corpse which she carries in lieu of a slab.

In order to carry over weapons, powers, and trinkets, Colt needs to infuse items with Residuum. Clearly there's a way to save some of this stuff, but it doesn't happen automatically. There's also the matter of Gold weapons, which require you to complete a side-quest to obtain them, something Colt literally doesn't have time to do every loop. However, it quickly becomes apparent that there are some items in Deathloop that you need to carry over between loops: for example, if you want to upgrade an ability slab, you need to already have that slab in hand at the start of the loop to pick up the next upgrade.

When this happens, Colt wakes up at the beginning of the day with everything reset - including any weapons, powers, and trinkets he managed to pick up during his last trip through the loop. The titular loop resets itself if the day ends before Colt can kill all eight Visionaries (including Julianna), or if Colt dies three times in a single mission. How can you carry over weapons and powers in Deathloop? Deathloop is a darkly comedic action-adventure game which sees assassins Colt and Julianna attempting to kill each other time and time again over the course of a single looping day.
