About Prism Siege
Movement is your lifeline in Prism Siege. Automatic weapons handle the attacks while you weave through geometric enemies and collect gems for the next upgrade. Build a useful combination of weapons and passives, prepare evolutions and face the bosses across eight campaign sectors. Endless survival and a UTC daily challenge provide new runs, while the workshop carries core upgrades between sessions. Pause when needed and resume a saved run in this browser. This standalone version is single player, and local progress does not sync across domains or devices.
