Tomb Raider: 10th Anniversary Edition was a remake of the original Tomb Raider that was under development for the PSP by the creators of the Core Design series. The project was canceled in 2006 and re – skinned as an Indiana Jones game, which was also postponed. Now, thanks to the Internet Archive and some top Tomb Raider fans, you can play this postponed game – sort of, a bit.
Not much of it to play with, honestly. The files released include levels set in Greece, Peru and Croft Manor, but no enemies and just a handful of interactive elements. All you can do is run and climb around them, throw switches, and ask what might be.
What happened instead was that Core Design was bought by Rebellion and closed in 2010, while Crystal Dynamics went on to develop and release their own remake, Tomb Raider: Anniversary, in 2007. Honestly, it seems to me like Crystal Dynamics ’Stronger remake was the best choice.
However, here is some history. The files are held by the Internet Archive, and there are instructions on how to set them up for play on the Tomb Of Ash fan site. You need to export the files to a specific location, install a patch, and have an Xbox 360 or PS4 controller before launching the game.
