Castle Cat 3: The Vegas Connection for the Sega Genesis is a homebrew port of the Flash game of the same name by the late Felix Wiesner. You once again follow Castle Cat, a cat whose head resembles a castle battlement, as he goes around various locales equipped with castle weapons like cannons and mace. This time, he's off to Las Vegas, Nevada, the land of dreams and gambling. He'll have to get past aliens, nuclear waste, slot machines, and Siegfried & Roy if he's gonna win it all.
Pepper-Color and Spikestuff together find out that this game requires more than just holding Right to win and conquer Vegas from the Luxor Las Vegas casino hotel as fast as possible.
