CastleStorm is one of two original pinball tables in the Iron and Steel pack, released in 2015 as an add-on for Zen Pinball 2, Pinball FX 2 and Pinball FX 3. This table is a pinball adaptation of Zen Studios' 2013 side-scrolling, physics-based real-time strategy game CastleStorm, in which the heroic knight Sir Gareth defends his medieval kingdom from an onslaught of Vikings, while winning the heart of their princess.
