Sega and Pulse Interactive will be releasing a new Dreamcast title in early '99, and although an exact title isn't known, ads have already begun running in several Dreamcast magazines. The ad simply says "Under Cover..." and shows a picture of a gun sitting on a chair. A dress that has two bullet holes in it is draped over the chair.
Pulse is mainly an Internet company, so it can be concluded that this game will have network features.
