This one flew under the radar when it was announced several days back, but in case you also missed it, the Mooncrash expansion for Prey received a free update called Rogue Moon. It's a tribute to some of Arkane's favorite games in the indie roguelike/roguelite/general permadeath space, adding new operator skins themed on Darkest Dungeon, Dead Cells, Spelunky, Don't Starve, Rogue Legacy, and Risk of Rain.
In a nice touch they've also shared a blog post in which members of the team talk about each game and why they love them, and in some cases how they served as inspiration for Mooncrash.
Thanks, RPS.
