Here’s a list of some ideas for floors that could take the elevator passengers to the world of Tower.
Virus floor - A floor that takes pace in Hospital from Virus. Going to this floor will cause the passengers to temporarily become Infected. Shortly after this happens, AI survivors will come and try to kill them.
Zombie Massacre floor - A floor that takes you to one of the locations from Zombie Massacre and it will have The Queen appear and attempt to attack the passengers, only to fail cause she is too big.
Little Crusaders floor - A floor that takes place in a world from Little Crusaders, it features Cornelius eating knights before turning his attention to the passengers on elevator and attempting to eat them, only for the door to shut on him.
The Stray Floor - This floor takes you to The Stray, where Kalleira will greet the passengers.
Game World Ports Floor - This floor takes you to the Game World ports, where attempting to queue any of the games gets you a message like “Queues are temporarily closed, try again later.”
