Guerrilla Games, you sly dogs! Much like The Last of Us teaser in Uncharted 3: Drake's Deception, the Dutch developer stuffed a Horizon: Zero Dawn hint in PlayStation 4 launch title Killzone: Shadow Fall – it's just taken us all this time to notice. One eagle-eyed Twitter user uploaded the embedded video, ensuring to copy game director Mathijs de Jonge in – who subsequently confirmed the clue.

"Well spotted," he replied. "The robot did undergo some changes, though." The reference is at the very start of the game, so you may want to avoid the video if you're touchy about spoilers. Let's be honest, though – no one in their right mind should be concerned about spoilers in a Killzone game.
