With 24hrs to go before the big official trailer premiere on YouTube, it looks like the Microsoft Store has let slip on the full trailer early, and it will launch on 23 July. HDR and 4K visuals will be supported, and the game weighs in at 7GB on the Xbox One.
The game looks to be only the single player portion based on the official description:
The classic first-person shooter from Crytek is back with the action-packed gameplay, sandbox world, and thrilling epic battles you loved the first time around – now with remastered graphics optimized for a new generation of hardware.
Crysis Remastered is coming to PC, PlayStation 4, Nintendo Switch and Xbox One on 23 July 2020.
