The initial area is a shut-down train entrance blocked off by danger tape. The player enters the abandoned train and travels through the empty train cars until they reach another abandoned facility.
Inside the abandoned facility, a key is required in order to progress through into the Deepsea Metro. From this room, a pressure switch activates an Inkrail into a storage room. Before entering the storage room, an equipper gives the Splattershot Jr. and Splat Bombs. While inside the storage room, there are various destructible crates as well as target boxes and balloons scattered throughout the room. The key is located in a box in the upper area. Exiting the storage room causes the equipper to take the Splattershot Jr. and Splat Bombs away.
Taking the key back into the abandoned facility opens the way to a train track leading into the Central Station.
"Up and at 'em, ya lazy whiffle-whaffle! This fight ain't over! Prepare for a royal whoopin'! But there's no honor in defeating an unarmed opponent... and you seem to have lost your weapon somewhere around here. And just where is... here... anyway? Last thing I remember, you were battling my protégé, Agent 3, in Octo Valley... when both of you were suddenly attacked by someone. And somehow we got marooned here... So, uh... hows about we call a temporary truce while we find a way to escape?"
"But where are my manners... I haven't even told you my name! I'm Cap'n Cuttlefish, leader of the legendary New Squidbeak Splatoon! And you are...?"
"... ...... *psst* This is the part where you tell me your name. By kracken... You lost your memory when you hit the ground?! You can't remember anything about yourself? Anything at all?!"
After the player has customized their character:
"Most interesting... I noticed you were humming the Calamari Inkantation right before you came to... Could it be? Has this heavenly melody been etched into your very soul?!"
"... ...... I'll take your stunned silence as a YES! I've heard tell of Octarians whose souls were etched by those squidtastic grooves... But that was a couple years back, during Agent 3's battle with DJ Octavio. Still... I can't shake the feeling that this is related somehow. In any case, sorry for siccing Agent 3 on you back there. Any fan of the Squid Sisters is a friend of mine! I mean that with all of my hearts. Now dust yourself off and find your land legs. We need to get moving! Let's find a way outta here!"
After proceeding to the next area:
"What in the devilfish is this place?! Proceed with caution... Hey - that's an Octarian vault! You need a key to open it. Being an Octarian and all... You sure this place doesn't look familiar?"
"Booyeah! That contraption back there gave you a weapon! Doesn't seem like any other Octarians are here... This place might be abandoned. Find that key! Ahoy - you found the key! Now head back and open that vault."
"That contraption stole your weapon back! Buncha hooey if you ask me! This looks a little sketchy, but... You're gonna have to check it out."
Trivia
The music in this area is the stripped back version of #5 thirsty. It transitions to the intense version after entering the key storage room, and transitions back after exiting. This place is the only one where the transition occurs.
There are 8-bit Cheep Cheeps at the very beginning of the station.
After completing the station, it cannot be accessed again.
