Revenge of the Savage Planet has officially surpassed one million sales, as confirmed by the developer on Steam. The sci-fi Metroidvania features split-screen co-op and a highly satirical and comedic nature, and it scored excellent reviews at launch. https://www.notebookcheck.net/New-3D-co-op-Metroidvania-packed-with-satire-surpasses-1-million-sales-in-under-2-weeks-as-Steam-reviews-reach-80-positive.1020573.0.html
I believe they specifically said 1 million players, not sales, because the game is available on subscription services...
Wait are we calling 3D platformers metroidvania now? Or is this just a buzzword used for clickbait
