Freewill, aka Miguel Chavez, has done some research at E3...and it seems that Bungie is working on not one, but two new games. Aside from Oni, Bungie's new 3rd-person action/fighting game, Freewill reports on two new titles called Blam! and The Action Sack.
Check out Freewill's original message to The Townhall for more info.
