Radical Spectrum: Volume 1

Radical Spectrum: Volume 1 is an endless arcade-style shooter set in the future city of Nucleusport. A band of aliens led by the careless Prince FaceBox attacks the city with radioactive waste from their polluted planet. You play as Doc DuBrane, the only person with the technology to fight back, and use his Prisma Cannon to absorb radiation dropped by alien ships and fire it back at them.

Collect and fire

You need to collect three units of the same color to fire, balancing risk and reward as you choose what to shoot. The game’s color-collecting mechanic adds a puzzle element, while speed and difficulty increase without limit.

Black radiation threatens both Doc and the ground. You must decide whether to destroy a UFO or target a black block winding through the grid; if black radiation touches the ground or Doc, the game ends. Collecting a color without checking what is coming next can leave you without good options, while firing at the wrong time can leave the ground at risk.

Manage the grid

Your choices also affect what you can collect: destroying more of the grid can help you pursue a high score, but leaves fewer options for collecting colors. The game requires attention across the screen, and each action affects your chances of survival.
