Prey's Mooncrash expansion—an entertaining, curious spin on the roguelite genre that isn't for everyone—has rolled out its second free update. Named Blue Moon, it adds four KASMA-themed weapons, three new operator skins, two hats for your mimic pets, obviously, and a host of bug fixes. 

Because who doesn't want a bucket hat or a propeller beanie for their mimic pet, eh?
