U4GM Where to Find Filtration System A Clean Dream Guide

Arc Raiders can be weirdly stingy with directions, so "A Clean Dream" turns into a little scavenger hunt the first time you run it. If you're trying to track down the ARC Raiders BluePrint objective without wandering in circles, think of the mission as two separate trips with one theme: get underground, touch the right interactables, then get out alive.

Queue into the Spaceport map and aim for the tunnel network under the launch towers. There are multiple ways down, but the most reliable entrance is the collapsed section southwest of the main tower. It's the kind of spot you'll recognise if you've already done other tunnel-related tasks. Drop in, get your bearings, and don't overthink the route. If you see signs of recent fighting or opened crates, that's not a dealbreaker. You're not racing anyone for "credit," you're just trying to tag the right objects and keep moving.

Your first checklist item is four containers. Here's the nice part: you can usually still interact with the mission containers even if somebody's already looted them. So if the place looks picked clean, run the tunnel line anyway and spam-check what's open. After you've counted four, go looking for a filtration system. The easiest one sits close to that same collapsed entrance area, near the sort of valve location players tend to remember. Walk up, interact, and you'll get the prompt. Don't hang around. Those tunnels invite third parties, and you'll feel very brave right up until someone hears you.

This mission won't let you be a hero and finish it in one deployment. You need to extract and return to Speranza, then redeploy to Blue Gate. Your target is the Maintenance Bunker, tucked near the Checkpoint POI, generally off to the southeast. A lot of players miss it because they expect a big obvious doorway. It isn't. Use the map text as a guide when you're close, then watch the angles as you approach. People camp this kind of choke point, and it's always when you're feeling "safe" that you get clipped.

Inside the bunker, head to the main room and find the huge cylinder-looking unit. That's your purification system; interact to monitor it. Then slow down—this is where folks mess it up by sprinting for the exit. Backtrack toward the stair corridor and check the small side room on the right, the one with lockers and a safe-breach spot. On a table you'll spot the blueprint stack; take the photo to lock in completion. After that, play it boring: grab the nearest extraction if it's open, and leave with your progress and your nerves intact, because that BluePrint in ARC Raiders step is only worth it if you make it home.Unlock powerful ARC Raiders Blueprints at u4gm.com, helping you craft stronger gear and advance your loadout quickly.
