One of the newest action titles on the Sega CD system is Psygnosis' sci-fi title, Microcosm. In this semi-innovative game, a whole army of shrunk-down enemies has been injected into the bloodstream of an important executive, and you must stop their assassination attempt from the inside.

You control a small fighter armed with an assortment of guns in a bland, first-person shooter that takes place inside the executive's blood vessels and bones.
