Take Two Interactive has purchased a 19.9% (let's just call it 20, okay?) stake in Bungie Software, as reflected in this press release. Bungie is best known for their Marathon series of FPS games, the Myth series of RTS games, and of course their two products currently in development, Oni and Halo. The press release goes on to say that Take Two's Jack of All Games subsidiary (a games distributor) will have exclusive rights to four upcoming games: Oni, Halo, and two more undisclosed products.
