A Tomb Raider game lost to time has resurfaced online and is playabe if you you're willing to compile some source code. "Tomb Raider: 10th Anniversary Edition" was a remake of the original game in development for the PSP by Core Design. Although the title was said to be "almost finished" according to the studio's manager Gavin Rummery, the game was scrapped and re-skinned into an Indiana Jones game which also ended up on the chopping block as the studio closed its doors in 2010. Crystal Dynamics focused on the multiplatform "Tomb Raider: Anniversary" and the "10th Anniversary Edition" became one of the unattainable Holy Grails for the Tomb Raider fanbase, until today. Now you'll be able to play the alpha version of the title and explore the Croft Mansion, Greece and Peru levels as long as you have Visual Studio and a compatible game controller. Although the levels feature no enemies, it's always fun to see what could've been.
