A moody twin-stick shooter with dynamic lighting, set in a dark sci-fi facility overrun by machines.
Underrun is made by Dominic Szablewski (phoboslab), with music by Andreas Lösch (no-fate.net), for the js13kGames competition. You fight through a dark research facility overrun by spider bots and sentries, and the real-time lighting from your shots and explosions shows you what is coming. Reach the terminals to bring the facility's systems back online and uncover what went wrong. It is short and intense, and the whole game fits in 13 KB.
