Crossbows and Catapults, also known as Battlegrounds, is a game of physical skill first released in 1983. It has since been published by several different game publishers including Lakeside, Alga (Brio), Base Toys, Tomy and currently Moose Toys (under the name Battlegrounds Crossbows and Catapults). In the game two sides, originally Vikings and Barbarians but later other names were used, build fortifications from plastic bricks then opposing players attempt to destroy each other's castle with rubber-band powered crossbows (similar to ballistae) and catapults firing plastic disks. In the most recent version launched in 2007, the two sides were Orcs and Knights.
