Ruins of Ark Polaris

The Ruins of Ark Polaris is a Salmon Run stage in Splatoon 2. It features an egg basket atop a platform and ride rails leading back up from the lower areas.

Layout
Ruins of Ark Polaris features an elevated platform in the center with two ramps leading to the ground. The central platform has two ride rails that both encircle half of the top platform. The two ramps provide an additional level in between the ground and the top platform. During low tide, the water recedes to reveal a shoreline with a central area and outer sandbar ring separated by a crescent of water.

Tides

 * During high tide, the water will rise leaving only the top level and the pathways below it, rending the lower ride rails inaccessible. Salmonoid will spawn from one of three paths.
 * During low tide, the water recedes to reveal a shoreline with a central area and outer sandbar ring separated by a crescent of water. The central area contains the basket and has ride rails leading to the outer ring. The outer ring also has ride rails leading to the center. The water separating the outer ring and center is considered shallow water, meaning Salmonoids can cross right through the area.

Trivia

 * The internal codename for this stage in the game files is "Shakeride".
 * The background features the tail of a crashed space shuttle, presumably the eponymous Polaris.
 * The space shuttle has worn-out text reading "PRIVATE PROPERTY" in English, as well as featuring giant letters spelling "ICA".
 * Some walls in the stage feature signs reading "Active Bear Area" in English.
 * With the exception of s for Splatfests that promote real-world brands, this is one of the few in-game appearances of any written human language.
 * The stage name could also be a reference to the constellations Ursa Major and Ursa Minor, as the star named Polaris is part of Ursa Minor.
 * There’s also the “Active Bear Area” signs that depict a larger bear (Ursa Major) on the sign above and a smaller bear on the sign below (Ursa Minor).
