It is actually the exact font used for the game. They just added a bunch of distressing to it. So if you want it to look identical to all the text, that's impossible, but you'd have to add your own distressing, grunge texture or whatever.
you download the file, extract the things inside of it onto your desktop, open My computer, search for the 'fonts' folder in the search bar (or whatever yours has, mac's have search bars, older windows pc's have that 'dog' thing, and new windows I think have search bars as well.), and put the files you put on the desktop in fonts, and now it should work! I hope this is helpful, since I forgot how to find the fonts folder,
