Grave is an open world survival horror game which pits you against the harsh wasteland and the murderer you are tracking down. The game was already confirmed for Xbox One and PC but luckily for PlayStation 4 owners it is now available.
From an announcement on the official website,
“We are excited to announce that Grave will be coming to the PS4 alongside the Xbox One in 2015. This means Grave will be available on Steam, for PC/Mac/Linux and available for digital purchase for Xbox One and PS4.”
The game is crowdfunded and the reason the developers thought it would be unavailable for PS4 is because they fell short of their target goal. However, Sony has revealed that Grave will come to PS4 sometime in 2015.
