Amusement parks seem to be the last place on earth where you can expect to run into a serial killer. The hero of Hello Guest is about to learn that you can’t be safe anywhere! He started his usual night shift patrolling the park when suddenly he realized he’s not alone here. At first he thought it was just a mischievous teen who sneaked in to take a joy ride on the roller coaster or paint a few graffitis on the fence. But the mysterious guest certainly has much worse – and bloodier – plans in mind… You have to be careful and inventive to avoid the most horrifying death!
