[i](note this is my experience and my recommendation coming from a network engineer but plenty of other internet warriors will come in here to tell you I'm wrong, I just want to call it now)[/i] Honestly I know plenty of people will come in here and tell you that you can run it on a 1 Mbps up connection but coming from a network guy, that is NOT recommended ... I would say a minimum of a 20/5 connection would be on the bare minimum I would ever risk. The higher the upload you have, the less likely you are to have as many issues as this game uses quite a bit of upload connection for the P2P hybrid mesh. Personally I would prefer somewhere in the range of 50/10 but I run mine on a 1000/500 connection myself but that is also because it's not only Destiny I use it for.
