Dishonored 2's E3 trailer, or at least a 30 second excerpt of it, appears to have leaked overnight. The good news is there are no spoilers. The bad news is there really isn't much context to explain what you're looking at.
NeoGAF spotted the trailer, which apparently came from someone's Twitch stream. That was taken down and the video above was quickly found.
Dishonored 2's first-ever gameplay demonstration during Bethesda's E3 keynote this evening should shed a little more light on what we're seeing above. This is the second time Dishonored 2 news has leaked before Bethesda's show. Last year, a streamed rehearsal of Bethesda's first-ever E3 news conference gave up Dishonored 2's existence, which was later formally announced during the show.
Dishonored 2, which continues the story from Arkane Studios' critically acclaimed Dishonored on the last console generation, will launch Nov. 11 on PlayStation 4, Windows PC and Xbox One.
