Twitter user Oops Leaks broke the news that according to the unconfirmed news he received, Kojima Studios' next small project may be a VR game, and it was created in cooperation with the famous VR expert Céline Tricart.

In addition, another user Genki_JPN said that on the J-Wave Radio program on January 21, Hideo Kojima specifically said that his challenging new game was not an AR work, and his expression seemed to be leaking (not AR, that's VR?). In addition, the show Kojima also said that the new game is not expensive, but it is very innovative and will surprise players.

It was just that he was busy working on Death Stranding. Now that Death Stranding is on sale, perhaps he'll regain his interest in VR. Considering that hideo Kojima's demo version of "Silent Hill" "P.T." is loved by many players, and if this game is made into VR, the horror atmosphere can also be greatly improved, which is really quite exciting.
