Metal Gear Survive has been delayed to early 2018. The game was previously slated for release in 2017, but according to Konami the development team needs a few more months to polish the title.
The game is currently being shown off to the press at E3 2017. According to a Konami representative speaking to Polygon, it will feature a dense single player mode in which players embark on a mysterious adventure, as well as a cooperative multiplayer mode.
