About the game

An original browser game by Zarocer.

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.

Controls

WASD, ZQSD or arrows: move the core. Hold the mouse button and move, or drag on a touchscreen. Weapons fire automatically; click, tap or 1–4 to choose upgrades. Esc or P: pause. Tab and Enter/Space: menus.
