Prey 2006 is a slightly gory boomer shooter with interesting topsy-turvy levels, gravity tricks, a few cool enemies and guns and powers, and a campy alien abduction / invasion story. It might be a little underrated in its genre. Definitely fun.
But Prey 2017 was more of a clever stealth action / psych horror title in the vein of Deus Ex and of course System Shock. Brilliant interconnected level design, a deep story, a good (though not super original) roster of guns and superpowers, some tricky puzzles, and a few interesting and enemies. It gets a good amount of love but I still think it deserves wider recognition as an excellent game.
