As the title says, I bought on Steam the Halo Master Chief Collection, but Halo 3, ODST, Reach and Halo 4 are not installed. I went and downloaded inside the game didn't work. Trying via Steam also didn't work. Steam's integrity check doesn't find anything wrong. So now I'm here, does someone know how to fix it?   submitted by   /u/Sepol133748   to   r/halo [link]   [comments]
