Microsoft will not be allowing cross play between the PC and the Xbox One, and because of that it will not be on the Xbox One when it releases on the PlayStation 4 next month. CEO Anton Yudintsev said ““Microsoft is not allowing cross-play completely; which means [War Thunder] cannot be on Xbox One.”
Yudintsev followed up that statement by saying “Cross-platform play is vital for a game like War Thunder because the install base of new consoles like the Xbox One and PS4 is too small for players to have an enjoyable experience.”
Yudintsev is hoping the game will still release on the Xbox One, but for now will be limited to the PC and the PlayStation 4 because of Sony’s more lenient attitude towards indie developers.
The Free-To-Play game is available in the UK and has been worked on closely with Sony development to patch any bugs or errors before releasing it globally.
