The official Transformers Fall of Cybertron website
has updated its characters section with two more characters. Now added to the site are the Autobot Jazz and Decepticon Soundwave. Jazz curiously has a different colored head to how he is depicted in game, with this version looking more like the Movie series version of Jazz. Both characters have their bios and special abilities given - Jazz has his well-publicized grappling hook, while Soundwave naturally gets the ability to eject minions from his chest.
Stay tuned for more official unveilings of characters - there are four more slots to go!
