Jarnasmal ties bullet-hell firepower to radio signal

Jarnasmal launched on Steam on August 17, 2026. The underground bullet hell makes a connection to the surface determine ammunition, damage and skill strength.

Jarnasmal: confirmed details

Strong signal supplies endless ammunition and maximum effects, weak signal degrades the blaster, and total disconnection leaves only a melee shovel. Walls and caverns block transmission, while repeaters can be upgraded for power, penetration and directional coverage. Deeper areas add denser projectiles and more dangerous technology. The official store listing credits Jarnasmal as developer and publisher.

What changed for players

Radio coverage turns level geometry into part of the weapon system. A safer repeater position can preserve firepower but slow exploration, while pushing beyond the network trades ranged strength for access to deeper loot.
