Guerrilla Games spent a decade making Killzone shooters before pivoting to Horizon, a post-apocalyptic open world of robot dinosaurs and a red-haired huntress named Aloy. The world's lore — mechanical beasts roaming a ruined post-human Earth — is one of gaming's best original sci-fi settings. The Decima engine's foliage tech made the world look stunning, and Aloy became one of Sony's most recognizable new protagonists.
