On display at Gen Con by Catalyst, the latest for Shadowrun were Spells and Chrome, an anthology of short fiction, and Sixth World Almanac. The latter book brings together for the first time in one place an overview of the Shadowrun setting, including a detailed timeline.
For Battletech, Catalyst had the newest book of mechs, Tech Readout 3085, associated record sheets, and the short fiction anthology, First Strike: BattleCorps Complition Vol. 2. There was also the Hexpack, which is a new system replacing the paper maps with mounted boards and overlay terrain hexes. The next iteration of the Battletech Introductory Boxed Set, which Catalyst was previewing at the show, will include the same map boards, as well as updated rule books, and two additional mech figures.
For Leviathans, still just a mock-up. Oh well…
