*UPDATE (01/08/17): Nintendo of America have since took to Twitter to reveal the name of the stage is Shifty Station and confirm it is only exclusive to the Splatfest stage rotation, but it can transform between Splatfests.

In case we didn’t have enough to be excited about this approaching weekend as it will see the first true Splatfest kick off for Splatoon 2, now we have something else to look forwards to!
Revealed by the official Twitter account for Splatoon 2, when the action kicks off, there will also be a new playable Twilight Zone to go with it, only it seems the stage itself is only sticking around for the duration of the Splatfest,, but should this change, we’ll be back to keep you updated.
