Honestly, I never been so hyped on TR stuff since Nicobass TR2 remake
Someone said to me that
Tomb Raider: The Dark Angel can be something like an animated short, but just rumors... Wish it'll be some kind of beta stuff (maybe the E3 playable demo like Caseum just said) or at least new info on AoD sequel!!!
There's a guy on Twitter (@jches16) that is apparently on the team who works at this secret project and he draws the Obscura Engravings (really cool drawings, btw) so this can maybe mean something on what's this all about.
