Lost Loot Machine Picks Up Unseen and Unchecked Loot

The Lost Loot Machine will get any loot you missed during your exploration of Kairos. The machine can only store loot if it has empty slots. It will start with six slots, but can be increased with SDU Tokens.

Cannot Pick Up Loot You Checked or Dropped

The machine will not collect loot you have seen or dropped from your Backpack. It is best to pick up any interesting loot for yourself to store or sell later.

How to Drop Items

Can Only Get or Trash Loot

In the menu of the machine, you can only trash items or put them in your Backpack. You have to go to the vending machines to sell your items or to the Bank of Kairos so you can store them for other characters.

Found in Major Cities

Extra White Loot Is From NPCs Fighting

NPCs Fighting May Give White Loot in Lost Loot Machine

The machine will also pick up dropped loot from NPCs fighting enemies. Since it is loot you did not see, it will be collected by the machine.

It would be best to regularly trash or take items from the Lost Loot Machine. This will make more room for other items to be collected. To note, the Lost Loot Machine is not a reliable method for getting strong weapons.

How to Increase Lost Loot Machine Slots

Use SDU Tokens in SDU Menu

Increase Lost Loot Machine Slots with SDU Tokens

You can spend SDU Tokens to add a slot to the machine. The price will be increased for the next slot you buy.

It is the least important upgrade in the SDU Menu. Upgrading your maximum ammo capacities will help you in long fights and hard bosses, the main methods of getting better weapons. Backpack and Bank slots will let you store more items.
