Ironclad is a side-scrolling shoot ‘em up for the Neo Geo CD. Use your war ship to save the Kingdom of Chop from the Iron Mask Republic. You can use three main blast weapons, which are upgradable when you collect more items, a charged attack available when Iron Clad is attached to your ship, three melee weapons, a bomber that clears all enemy bullets, and varying shooting patterns. Stages are selectable, and there are multiple endings.
Another version was developed for the Neo Geo as an AES-based cartridge, but was never released in this form. This cartidge version is the one that was eventually released on the Wii's Virtual Console.
