Nullbreak Protocol

Break into the system. Clear every room. Go deeper.

Nullbreak Protocol is a sci-fi arcade roguelite built around a single, escalating loop: launch your core, shatter every block in the room, survive what the room throws back. Each run pushes you further into the system — and the system does not stay the same.

Run the protocol

Every run is a descent. Rooms escalate in density, hazard, and pressure the deeper you push. There is no win screen in the endless descent — only how far you got, and whether the next run goes further.

Build your run

Between rooms you draw protocols — modular upgrades that reshape how your run plays. Stack them, combine them, specialize. With a pool of over 20 protocols and stacking effects, no two runs resolve the same way. Side cannons, pulse lasers, shockwave radius, overclocked speed — the build is yours to assemble.

Read the room

The system fights back. Turrets track and fire. Laser nodes sweep the arena. Explosive blocks chain. Shielded blocks refuse to break. Regenerators heal their neighbors, phase blocks flicker out of reach, mirrors and accelerators bend your core's path. Fifteen block types, each one a different problem to solve under pressure.

Push the depth

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.
