Just imagine some fangs and you have a good idea of what to expect, based on what we know so far.

The recently acquired Sucker Punch seems to be taking a cue from Rockstar Games with inFamous 2: Festival of Blood, a vampire-themed expansion for this summer's open world adventure that explores the "darker" side of the inFamous universe.

News on Festival of Blood arrived at Sony's Gamescom press conference today. In the trailer, Cole was sporting some mean ol' fangs.

Rockstar Games pulled a similar stunt with Red Dead Redemption and the super great Undead Nightmare. If you haven't played Undead Nightmare, you've screwed up--it's terrific.

Festival of Blood arrives in October with "hours" of new gameplay.
