About SIGNAL ZERO
SIGNAL ZERO is a sci-fi arcade shooter built around ten five-minute sectors, each with its own arena and its own mix of enemies. The pace is relentless: waves grow increasingly dangerous as the timer counts down, and two of those sectors — 05 and 10 — demand that a boss be defeated before time runs out. Between sectors, ship upgrades keep the challenge from becoming a wall. The result is a tight, structured survival loop that rewards both quick reflexes and deliberate upgrade choices.
How to Play SIGNAL ZERO
The goal in every sector is to stay alive for five minutes. Sectors 05 and 10 add a boss condition: the boss must be defeated before the timer hits 00:00. Dodge drones, recover energy, and after clearing a sector, choose an upgrade for your ship. Ten sectors in total, each with its own arena layout and enemy composition.
