98xx is a horror-themed game built around the interface of a fictional late-90s desktop system. Players interact with a simulated computer environment, where folders, applications, and utilities mimic the look and behavior of classic operating systems. On the surface, everything appears familiar: a web browser, media tools, and small games are all accessible. As the player explores the system, certain programs begin to act in unexpected ways. Graphics distort, sound clips play without warning, and files change or appear on their own, signaling that something is wrong beneath the surface.
Progression in 98xx depends on close observation and experimentation. Seemingly harmless software sometimes hides alternate functions, and specific combinations of actions can reveal new content. Players must search for clues across different programs, decode corrupted messages, and use in-game tools to unlock deeper layers of the system. There are no clear objectives or guides — instead, discovery happens through trial, error, and curiosity. The experience becomes increasingly surreal, with the system behaving less like a static interface and more like a living environment.
The aesthetic of 98xx uses a low-resolution interface that imitates older personal computers. Animations are limited, but carefully timed visual glitches and screen disruptions change the feel of the interface. The audio design includes mechanical hums, abrupt interruptions, and distorted speech that interrupt normal activity. These effects build tension without traditional horror visuals. The game relies on contrast between nostalgic design and abnormal behavior to create discomfort. Through slow escalation, 98xx creates a psychological space where the interface itself becomes unpredictable.
