I found a couple of download sites for with Tomb Raider 2013 saves here
http://www.savegameworld.com/pc-tomb-raider-2013-save-game/and here
http://www.savemygame.fr/en/pc/t/pc-tomb-raider-save-game.htmlI've never used either of these websites before -- Google found them.
I'd recommend the savegameworld.com site over the other one because savemygame shuttled me around to different webpages when I clicked on what looked like a download link.
With
***savegameworld*** all I had to do was click the big red download button.
Their instructions are:
Copy files into game folder
C:\Documents and Settings\All Users\Application Data\R*L**D*D\%UserName%\%Appid%\
C:\ProgramData\R*L**D*D\%UserName%\%Appid%\
Of course before you copy the save files you have to extract them from the zip (or rar) file first.
It looks like 5 different people contributed their saves at the
http://www.savemygame.fr/en/pc/t/pc-tomb-raider-save-game.htmlwebsite, so keep that one in mind in case you need saves for a different version of the game.
But you may want to get the saves from
http://www.savegameworld.com/pc-tomb-raider-2013-save-game/because they offer a zip download which can be scanned for viruses with online scanners.
I don't have this game (don't want it either) so I can't give detailed information on installing. All I can tell you is that if you extract the zip file that's called
[PC]Tomb Raider 2013 by REBELYELLIEX.zip
you get a folder with another folder inside it, and inside that there are folders labelled 1 2 3 5 6 7 8 9 10 11 12 13 15 16
I assume these folders are the separate saves, but I don't really know. Maybe the number signifies the chapter? It looks like this game has a complicated save system, with two folders that are nowhere near each other. Maybe someone who's played the game can help you.
If you find the save folders for the game on your computer, check what the file structure looks like.
If you need further help and no one else posts here --
Usually the Hints forum handles save games and instructions for them, but since this is a "Darkside" game, you may want to ask in there instead.
