A user has uncovered some leaked data sourced within the God of War: Ascension disc that gives us insight on never before revealed details about The Last Of Us multiplayer and single player. Uncharted3Hacks.DE, a sketchy looking site, decodes what seems to be extensive details regarding single player weapon craftsmanship as well as multiplayer weapons and boosters for The Last Of Us. All the info below is from a March 13th build so the user speculates some things may have changed.
Update: This is a warning to those of you that are interested in the story of The Last Of Us. The cutscene titles of the game were leaked in the strings that were removed in the original post seen below, however the information is still out there. The leaked titles will spoil the entire game.  Check out the log below.

I decided to look inside the game files of God of War: Ascension for the TLOU demo countdown files, and I ended up finding it in the Naughty Dog engine. This means there were some files left behind from the actual game that can reveal new things.

 

These were mostly text and code files, with some image files, so it wasn’t very big compared to GoW:A, and it revealed many things.

 

NOTE: Everything here is from a month-old (or more) build, as of Mar 12 2013, so any information is not final and will most likely change by the time the game is released or when the info is revealed.
