Apex Legends Single-Player Game Plans

New job listings such as this one for a "Hard Surface Artist" reveal Respawn Entertainment is incubating a new single-player first-person shooter using the Apex Legends setting (thanks Dexerto). Plans for a single-player adventure from Respawn surfaced last year, but there's no way of knowing for now if these news bits intersect, or are separate. Here's what the listing has to say about this "brand new Respawn single-player adventure":
This new single-player title is a developer’s dream playground with the freedom to innovate made possible by the unique universe it inhabits. Our critically acclaimed, multi-platform games have always established a “fun comes first” sensibility created with the notion that great ideas can come from anyone, which allows creativity to shine and individuals to shape the game in meaningful ways.
