About Nullbreak Protocol
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. Run the protocol 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. Build your run 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. Read the room 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. 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. Make it yours Done with the built-in challenges? Build your own rooms with the in-game editor and drop straight into them. Your layouts, your rules. Features Fast-paced sci-fi arcade roguelite - easy to start, hard to master 20+ stackable protocols for deep, run-defining builds 14 distinct block types, from turrets and laser nodes to phase and mirror blocks Endless descent with escalating difficulty and depth-based scoring Persistent meta-progression - unlock protocols and bonuses across runs Build and play your own custom rooms with the in-game editor Full English and German language supportRead more
