Shadow of the Tomb Raider

Tomb Raider 12 is the upcoming sequel to Rise of the Tomb Raider.

Square Enix inadvertently confirmed the game during E3 2015.

It was later confirmed that the Game would be directed by Ian Milham, who served as the Art Director for the Dead Space series and Creative Director of Battlefield Hardline.

It is currently unknown if Rhianna Pratchett will return to write the game, or whether Camilla Luddington will reprise her role as Lara Croft.

If the ending of Rise of the Tomb Raider leads into the third game, then it takes place in Yucatan Peninsula, and Kennard Montez has something to do with the story.

Gameplay
The game is expected to be a third person action adventure game, with emphasis on puzzles,  much like the previous games in the timeline.

Development
Development on the game was confirmed to be in early stages of development as early as at least June 2015.
