In 1980, Sierra released their first ever game as well as the first ever adventure game with graphics: Mystery House! This game tasks you with staying alive in a house with a mystery killer and finding them before you get killed too.

In this video walkthrough, I show you how to get the information to find the killer, stay alive, confront them and get the treasure! Keep in mind that this is very antiquated and was literally the first of its kind but it's still a blast to play.

It's a short game but is available for free since 1987! You can check it out at archive.org/details/Hi-Res_Adventure_1_Mystery_House_1980_On-Line_Systems
