Table of contents
Sector 1: Corruption

You wake up in the void, standing on a thin tentacle-esque platform. Follow it to enter a vent, then keep walking inside until you drop into a room with lasers.
Look to the right and pick up the Data Helmet, which lets the protagonist analyse their surroundings, which are full of items. Run inside the vent from where you picked up the helmet to skip the lasers.

Follow the path and enter the second room with lasers. After avoiding them, the game introduces the physics-based object movement; use the left click to hold and move objects around to clear your path.
Don’t fall into the puddles while avoiding the lasers. This room can be tricky at first, but through trial and error, it can be done.

Enter the highlighted pipe, and then conclude the first Sector.
Sector 2: Possession

In the second Sector, you’ll be greeted with an electrified fence along with a door. The fence is lethal, so avoid touching it. Return to the entrance and jump on the platform to your right.
Move forward on the platforms to find an alternate path to go over the fence. Remove the Power Core with green lines to unlock the Charge ability.

With Charge, the protagonist can now move heavy objects efficiently. Later, remove the giant metal barrel in your way to enter the next vent.
After finding your way out of the vent, enter the barrel production room. Later, behind the conveyor belt, see the weight system. Push the barrels into the weighing station with the charge ability to pull up a platform to your right.

In the next area, there will be a turret that awaits you. Below, find the tunnel to sneak up behind it and then use Charge to override it.
Return to the platform to find another vent with a laser trap. Avoid the laser and continue moving forward to exit the vent. In the next room, override the turret before you.

Proceed through the room by using the platforms to avoid lasers and puddles. The next turret is unlike the others; it’s connected with magnetic anchors that protect it from Charge.
Sneak behind it and continue moving to the room’s end to discover a fixed turret. Now, dismantle its head to unlock the ability to corrupt all turrets.

Return to the initial magnetically locked turret and hack it to break the metal lock. Then, through the now-unlocked door, exit the Sector.
Sector 3: Incursion

Once you’re in the third sector, enter a vent covered by a broken plank; destroy it using the Charge ability.
You will find a Dispenser that can be used to create power cores. Use the switch to its right to spawn one. Carry it to the previous room and put it inside the pump.

Use the switch above to unlock the next room, and wait for the water levels to decrease. Pick up the Cargo Clamp at the end.
Once you pick up the clamp, security measures will be triggered, and tens of lasers will cover the entire room. Avoid them and then return to the Dispenser

Override the turret. Then, merge with the Convoyer Rail to enter the next area through a giant pipe.
Remove the concrete blocks from the wooden platform to reduce its overall weight so it can rise with the water. Enter the vent at the top, avoid the laser, and unlock the bottom fence by removing the locks.

Jump down on the cardboard boxes and override the turret. However, this triggers security, and lasers will spawn throughout the room.
If you’re having trouble with the lasers, you can merge with the turret and destroy them; don’t forget to override it after the room becomes safe. At the end, open the ventilation shaft and follow the path to enter the next area.

With mines, turrets, and lasers, be mindful of your next move. To the opposite of the first platform with three mines and a magnetically anchored turret, climb up the plank to reach the vent above.
Drop down from the vent and use the lever to push the anchored turret into the mines. Return to the first platform and merge with it to break the two turrets before you. Additionally, break the construct to your right to open the floodgate.

Jump on the mobile debris in the water to get to the second platform. Subsequently, you can find the Sector’s exit.
Sector 4: Expansion

The fourth Sector begins from the vent in Sector three. Ahead, merge with the turret and destroy the rest with it. Additionally, static lasers will appear from this area.
Use the two Cargo Clamps and a traffic cone to then block all the lasers that restrict the entry point to the next room. Jump down and override on the final turret.

Remove all the barrels from the elevator with Charge. Wait for it to rise, then drop off the elevator when the security system activates. Turn the system off by removing the yellow battery, then drop down into the vent.
Progress through the next area normally. Now, you will enter a room with two turrets and a maintenance robot. Override the turrets and then climb up the small bridge above by jumping on the debris to your left.

Free and take the Damaged Drone to use the maintenance drone and cross the gap. Later, a turret will destroy the drone once it’s above a ventilation shaft to conclude Sector four.

Sector 5: Ascension
After falling into the ventilation shaft, immediately drop down from the ledge and merge with the turret. Break the metal lock before the crusher completes its job.

Rush into the vent and continue moving forward. However, an invisible gap will drop you into a room with a boss; no way out this time.
It’s a survival game. Swifty move around and wait for the power core covers to roll up. Removing power covers further empowers the arena with laser traps, mines, and turrets, which can only be disabled by taking off their cores.

For the final power core, disable the turrets and wait for its cover to open. Once you remove the final power core, the boss shuts down, and a vent opens up.
Go through the vent and follow the path with thin powerlines to find a bio suit. Pick it up, and Sector five will end.

Sector 6: Damnation

As the final Sector starts, you are dropped into a radioactive area with the bio suit on. Additionally, you can’t sprint with the suit. The visuals will start to alternate between normal black-and-white and colour.
Lastly, follow the light at the end of the tunnel, and the credits will roll.

This concludes our complete walkthrough for Sector Zero, with all the Sectors and how to complete them.
