A lost Atari 5200 prototype returns
Castles & Kings was demonstrated in 2003, then canceled before it could reach players. More than two decades later, Mean Hamster Software is bringing the rediscovered game back for the Atari 5200.
The 2026 revival is credited to Jim Leiterman and John Swiderski. More screenshots, gameplay details, and release information will be shared as development continues.
