The new single, produced alongside The Weeknd-collaborator Illangelo, follows last month's Chris Lake collaboration "A Drug From God", which marked the debut outing of her AI girl group NPC.
On top of releasing the new song - which soundtracked Rocket League's season five Rocket Pass trailer last month - Grimes shared another post on Instagram announcing, "And so the BOOK 1 era begins."
It looks likely that Book 1 could be Grimes' forthcoming album, as the video description states that "Player of Games" is "Chapter 1 of Book 1 by Grimes."
Back in July Grimes revealed that her follow-up to last year's Miss Anthropocene album is a "space opera" that results in a lesbian AI romance. In September she added that her new album is "by far my greatest work that I've ever done"
