Resident Evil 6's live gameplay demo from Capcom's action-packed gamescom 2012 press conference has made its way online. Watch it in full, although sadly off-screen, through the break.
Capcom Unity posted this video. Don't ask me difficult questions about why they don't have direct feed access.
Resident Evil 6 launches in November on PlayStation 3 and Xbox 360, assuming you haven't watched the entire game on YouTube by then.
