  • Keep moving in a circle while firing — standing still gets you swarmed.
  • Prioritize enemies that split apart before they multiply.

About Underrun

Dive into a glitching neon underworld where you play a lone netrunner hunting a rogue AI in this slick twin-stick action shooter. Underrun pairs satisfyingly chunky gunplay with environmental puzzles, weapon pickups, and corridors of corrupted programs that swarm, snipe, and split apart under fire. The hand-tuned pixel art and chromatic glow lend each room a striking cyberpunk identity, while tight movement and generous checkpoints keep the pace aggressive without ever feeling cheap. Compact enough to finish in a sitting yet dense with secrets and weapon synergies, it is a memorable browser action game for fans of arcade-style shooters with a story.
