A fast-paced action roguelike where time is your vital resource. Battle digital hordes, harvest fragments to survive, and use Chrono Tokens for deep, ARPG-style weapon customization, traveling through planets to save the dimension.
Protocol:Chrono
SteamProtocol: Chrono is a fast-paced action roguelike with bullet heaven DNA. There’s no health bar — your lifeline is Time, constantly draining away. Every second matters, every kill buys survival, and every mistake brings your end closer.

You are the Chronal Agent — a security process deployed into a simulation suffering Terminal Entropy. The system is breaking, data is leaking, and corrupted shadows — hungry processes that feed on time — will do anything to terminate your execution.
Travel across 10 unstable planets (sectors), push back corruption, and stabilize the Kernel before everything is erased.

Forget potions and hearts. In Protocol: Chrono, your “HP” is a timer that never stops ticking down.

You don’t just pick weapons — you compile a build.
Use Chrono Tokens to unlock slots and equip upgrades that reshape your playstyle: multipliers, effects, synergies, and combinations you can adapt on the fly.
Explosive thermal payload chains? A defensive feedback field? Autonomous daemons holding the line? Your build, your rules — mid-run.

The run ramps into a frenetic climax:
