The 2012 E3 expo doesn't formally kick off until next week in Los Angeles, but GameTrailers has got the jump on a few new video reveals from several of the major publishers.

From Bethesda is this impressive new gameplay trailer for Dishonored, the Steampunk first-person shooter in the works at Arkane Studios. The clip runs for three-minutes and features lots of stealthy assassinations set to a haunting rendition of the timeless sea shanty "Drunken Sailor". Check it out below (or here on the HD video page).

We'll be checking out the game in greater detail at the show too, so stay tuned for more as we have it.
