It seems Square Enix has registered two new domains for new Tomb Raider titles called Rise of the Tomb Raider, and Lara Croft and the Temple of Osiris. For now, we can’t be sure are these titles new games, comics or something else. However, Lara Croft and the Temple of Osiris seems to have a bit similar naming to Tomb Raider spin-off “Guardian of Light” which was released on many platforms.

If these are new games waiting for an announcement, we will be likely hearing more about them at E3 2014. It’s also possible Square Enix is just registering these domains to save them for future plans.
