Lara Croft and the Temple of Osiris will be available to download on 9th December for PC, PlayStation 4 and Xbox One, publisher Square Enix has told Eurogamer.
The co-op adventure is a sequel to the well-received Lara Croft and the Guardian of Light, and follows the grown-up Keeley Hawes-voiced Lara as she unravels a new Egyptian mystery.
Temple of Osiris can be played through entirely in single-player, but also supports co-op play for up to four people. In that mode, you take on the roles of Lara, fellow explorer Carter Bell and, naturally, the ancient Egyptian gods Horus and Isis.
It's being developed by regular Tomb Raider studio Crystal Dynamics - which is also creating a sequel to last year's full Tomb Raider reboot.
