So my friend to failed to download Dota 2, and I was wondering if I could help him out. Will it work if I copy Dota 2 on a USB and let him paste it on his PC? If so how?
Wait what? Steam failed to download it? Uuuuuuuhm. I think you should try deleting and redownloading again, because that shouldn't happen unless the servers were fucked when you were trying.
Otherwise, you might be able to put the files in under /Steam/Steamapps/Common/Dota 2 or something to that extent, and let it resync with the program.
