Guerrilla Games on Horizon and Killzone Shadow Fall on PS5
On the day of PS5's launch in selected countries, Guerrilla Games boasted of how its older games work on this next-gen platform. Specifically, the devs mentioned Horizon Zero Dawn and Killzone Shadow Fall.

Guerrilla Games has reported via its Twitter profile on how its games designed for PlayStation 4 work on PlayStation 5.
Both Horizon Zero Dawn and Killzone: Shadow Fall have been included in an extensive list of games compatible with next-gen consoles. While the former allows for the transfer of saved game data from PS4 to PS5, the latter will offer up to 60 fps on the Japanese giant's next-generation console. Apparently, Aloy's adventure will continue in 30 fps.
