Splatoon 3 – Doors, Doors, Doors! And More! (Doors) Walkthrough 

To begin, progress through the security gates, past the first checkpoint, and shoot the splat-switch to enter the building ahead. Though obscured from the outside, there will be a mobile Octarian waiting for you inside. Quickly splat them, and then hit the second splat-switch.  

Move through the newly opened door but turn around before you move forward. Cover the grey pillar in ink and climb the building you just left. There will be an orange crate at the top containing a key. Then, drop back down and proceed into the next building. 

Another mobile Octarian waits in the room beyond, with a third encased in a vault. With the key you acquired, move to the vault and be ready to splat the Octarian inside the moment the walls come down. 

Splatoon 3 – Enter The Complex 

With the Octarian vanquished, move along the thin walkway to enter the main complex in Splatoon 3’s Doors, Doors, Doors! There is a flying Octarian locked in a vault to the right, but you don’t yet have the key to unlock it. The goal will be just ahead, but it is presently unreachable across a large chasm. 

Though there initially seems to be no other way forward, look down and the path will present itself. There is a grate below your feet in the main complex entrance, which you can drop through in squid form. Do so and shoot the orange crate to acquire another key.  

Return to the floor above and use the key on the Octarian-imprisoning vault. Two more Octarians lie in wait in the room beyond, but you should be able to make quick work of them. Hit the splat-switch in this room to open a path to the outside.  

Turrets And Towers 

A turret Octarian out here will be able to swiftly gun you down, but there is a way to quickly deal with him in Splatoon 3’s Doors, Doors, Doors! Shatter the closest orange crate to equip a Reefslider. Take cover, and when the turret is between shots, aim the Reefslider at the Octarian and take them out. 

Unfortunately, the Octarian was not hoarding a key. But with them out of the way, you can climb the grey pillar behind you to get atop the main complex. Once at the top, ink up the thin walkway and turn into squid form, allowing you to gain enough speed to make a jump across to the structure opposite. Shatter the orange crate here and grab the key inside. 

Jump back across to the main complex roof, then drop through the grate on the right side of the roof to access a hidden walkway. Take out the hovering Octarians and hit the splat-switch they are guarding, then jump across to the newly-accessible platform. 

An Octarian sniper can make your life difficult here. Carefully move from cover to cover, then splat the sniper when close enough to receive the level’s final key. Climb the wall across from the sniper and hit the two splat-switches, creating a pathway to walk on. Unlock the vault and shoot the switch beyond to raise part of the bridge to the goal. 

Return to the main complex and use your remaining key to access a switch that will raise the rest of the bridge. Then proceed across the bridge at your leisure to complete Splatoon 3’s Doors, Doors, Doors! And More! (Doors) level.
