UNRAVEL THE MYSTERY
In the mid-1980s, the Hogo computer operating system was considered the next big thing. It powered cutting-edge computers by providing stunning color displays, generating amazing sound, and supporting huge 426x240 pixel display monitors. It really was the future.
And then practically overnight, Hogo OS disappeared.
What happened is one of the biggest mysteries of the 1980s. Rumors say that an evil mastermind attempted to use Hogo OS to take over the world, and was only stopped by the bumbling actions of a complete idiot. Those rumors are true.
The year is 1985. And you are that idiot.
A FULL OPERATING SYSTEM EXPERIENCE FROM 1985
Dum-Dum is equally a simulator and an adventure game. You must solve puzzles and decipher clues to uncover its secrets.
The interface is a full simulation of a fictional computer operating system: Hogo OS 1985 Edition. It includes everything you'd expect to find on a computer from 1985. Numerous games like Solitaire 1985 and Hogoworm Dungeon. Creativity applications like Animator and Piano Composer. Digital books, interactive stories, and features to customize your desktop. There's even a simple working BASIC programming language.
But digging a little deeper will uncover new secrets, hidden activities, and quests. Part of the fun is exploring and uncovering the many programs and features of Hogo OS.
Ultimately, the main story requires you to figure out how to best use the Hogo operating system to solve a puzzling mystery. Hogo OS 1985 Edition is your key to interacting with quirky characters, uncovering the strange history of the Hogo Company, and saving the world.
Or...you can ignore the main story for awhile & just enjoy the open-ended sandbox gameplay. That evil mastermind isn't going anywhere.
