Square Enix has officially released the teaser trailer and has previously announced that the game will be launched at a major event in 2018, but the source code from the game's website revealed that the game should be officially launched on September 14th with more details coming on April 27th.

The teaser for the announcement and the trailer which you can check out below does not reveal much except for the "Shadow of The Tomb Raider is the climatic finale of Lara’s origin story" tagline, which suggests that there might not be any further Tomb Raider games focused on Lara's origin story.

In any case, we should get full details and probably a more detailed trailer in April.
