Iridium Is a new upcoming frantic 2d shoot ’em up with huge levels and truly massive enemy ships. Mixing game styles from Uridium, Xenon 2, Nemesis and R-Type. In Iridium the basic concept of the game is simple. You control a single-seater fighter craft and your mission is to intercept fleets of enemy fighters and inflict a crippling amount of damage on them. That is the main idea, but things are never that simple in shoot em ups. The game will be released this summer on Steam.
