What We Left Behind is one of Tian Wen's first few missions that players will be able to complete in Arc Raiders. Similar to a lot of the quests in the game, players will have to go on three separate runs and search for different things. A few tasks in this quest can be considered difficult, not because they are challenging, but because they might confuse players. The guide below offers a step-by-step walkthrough of the quest and the rewards players will get in Arc Raiders.

What We Left Behind Quest Guide in Arc Raiders 1

There are three objectives for this quest, which require you to run a mission on Dam Battlegrounds, Buried City, and Spaceport. You do not need to bring anything for these expeditions, so you can go with a free loadout if you don't want to lose your items.

Parking Garage - Buried City

Starting with the Buried City map, once you spawn, make your way to the Parking Garage, which is located around the middle of the map near the Hospital. Once you reach the garage, go over to the elevator, which should have a breach option. It doesn't matter which floor you are on; it's going to be the same for all the floors. However, there are no Pops or Fireballs on the ground floor, so you should ideally go there.

After breaching, head down the zipline, making sure you close all doors behind you so you can slow down any players that will come after you. At the bottom, you will find a Raider Camp where you can search two containers to complete this objective. There is a chance that a weapon crate will spawn here as well, which can drop Purple Rarity weapons, so be on the lookout for that. Once you are done, you can jump down from the window up ahead, turn right twice, and go down the metro station to extract.

South Swamp Outpost - Dam Battlegrounds

For the second objective, make your way to the Dam Battlegrounds and go to South Swamp Outpost. There should be a building here that is similar to the shape of a silo.

There are multiple open gaps that you can enter from. In one corner, you will find an item you can interact with, and this will complete this objective.

Container Storage (Bilgunn's Hideout) - Spaceport

For the last objective, start a match on the Spaceport and go to the area to the right of Container Storage. Even if you are on the Container Storage side, there is a part of the wall that is broken, and you can go over to the other side from here. You can also climb up the wall from here, which is another way to reach the objective, but might leave you too exposed for a sniper shot from an enemy Raider.

Approach the metal container that is on the wall, and there should be a ladder that leads up. Go up and grab the notes, and you can extract to complete the mission in Arc Raiders.
