Break into the system. Clear every room. Go deeper.
Nullbreak Protocol is a sci-fi arcade roguelite built on one escalating loop: launch your core, shatter every block in the room, survive what the room fires back. Every run drives you deeper into the system - and the system never stays the same.
Every run is a descent. Rooms tighten in density, hazard, and pressure the further you push. There's no victory screen down here - only how deep you got, and whether the next run goes deeper.
Between rooms you draw protocols - modular upgrades that rewrite how your run plays. Stack them, chain them, specialize. With 20+ protocols and stacking effects, no two runs ever resolve the same. Side cannons, pulse lasers, shockwave radius, overclocked speed - the build is yours to assemble.
The system fights back. Turrets track and fire. Laser nodes sweep the arena. Explosive blocks chain. Shields refuse to break. Regenerators heal their neighbors, phase blocks flicker out of reach, mirrors and accelerators bend your core's path. Fourteen block types - each one a different problem to solve under pressure.
Clear rooms, bank fragments, unlock new protocols and run-start bonuses. Persistent meta-progression means every run feeds the next. Your record is depth - beat it.
