10-103

In the video game 10-103, you play the part of Specter 8, a professional agent who is sent to an underground research facility that has had a breach in its containment system. Staying in contact with your operator, Morpho, through radio communication, you’ll fight off terrifying undead enemies, use elevators to explore the depths, and try to survive the chaos. Despite its short runtime, this small horror shooter packs plenty of tension for fans of sci-fi thrillers.

Overview of 10-103

10-103 is a short indie game that combines sci-fi, horror, and action elements, developed by Nerdspartan in just 10 days for the Scream FM 2020 game jam. The title refers to a police code “10-103,” which means “disturbance”—a fitting description for what unfolds.

You play as Specter 8, dispatched to the Aegis Research Facility, where an outbreak has unleashed Class-4 or higher entities. Your mission: investigate, fight through the infected, and maintain communication with headquarters.

Gameplay & Experience

Character Controls

• Move: A/D keys or left/right arrows.

Radio Communication & Combat

Combined with sudden encounters against grotesque enemies, it creates a claustrophobic and tense atmosphere that forces you to balance action and survival.
