About Granny GTA: The 500M Yen Inn Heist
A 3D crime action game starring a grandma.
Mission: Inn Raid
Start at home. Granny and Tanaka go to the inn to collect money, but the inn's granny owner treats them terribly. Grab the nerve gas bomb at home, take down inn staff to steal an employee uniform, rewrite the kitchen's cooking process to make dangerous food, and plant the bomb in the hot-spring boiler room to punish her. Then Granny starts with a shotgun, a handgun and a kitchen knife. Raid the inn step by step in a large open-world city: (1) wreck the power panel to kill the security cameras and shutter, (2) take the vault key from the inn manager, (3) open the vault room, (4) break the safe with the crowbar, drill and dynamite you collect around town, and then (5) survive the Gatling-gun granny who comes for you! Then jump in the getaway car, shake off the police and reach a distant countryside station. Ride the train to Shibuya and turn the cash into crypto at an exchange!
Endless Shibuya Missions
Shibuya is packed with pedestrians, shops and cash exchanges. Robbery and collection missions keep coming, and you convert every haul into crypto. There is no ending. A minimap and an overhead destination tag guide you.
