CryZENx continues to work on porting The Legend of Zelda: Ocarina of Time to Unreal Engine 4 and adding new features. He posted a video yesterday, for example, in which he demonstrated the cooperative passage of some locations.
Unfortunately, the published beta does not yet include a co-op remake, but CryZENx promises to add it soon. The modder is also working on converting The Legend of Zelda: Ocarina of Time from Unreal Engine 4 to Unreal Engine 5.
Nintendo has yet to send the developer a chain letter, which is surprising.
