Final Fantasy VII: Revelation may be coming to Switch 2 in April, but there's another game they want you to play in the leadup.
A Switch 2 version of Crisis Core: Final Fantasy VII Reunion was revealed at the end of a recap trailer for Revelation, and will be out today. The remake of the PSP game originally launched on Switch in December of 2022, but the Switch 2 version will offer a higher framerate and resolution.
