The lineup runs from May 5 to May 19 and includes day-one releases such as Forza Horizon 6, Subnautica 2, Mixtape and Outbound across cloud, console and PC.
Other additions include Final Fantasy V, Doom: The Dark Ages, Elite Dangerous and several Game Pass Premium titles, with some games also optimized for handheld play.
Xbox said five games, including Planet of Lana and Galacticare, will leave the library on May 15, while updates and in-game benefits continue for titles such as Sea of Thieves and World of Warships: Legends.
