THE SYSTEM IS CORRUPTED. BREAK THE LOOP.

Plunged into a ruthless cyber-apocalyptic world, you have only one objective: purge the infected networks. The system is relentless, death is inevitable, but your power survives every failure.

KEY FEATURES

⚡ The Urgency of Short Sessions No time to breathe. Incursions are calibrated for high-tension runs lasting 5 to 8 minutes. Perfect for a quick, adrenaline-fueled session on the go, or long sleepless nights spent optimizing your gear to reach the next boss.
⚔️ Pure & Demanding Hack'n'Slash Click-to-move navigation, fast-paced melee combat, and visceral crowd control. The rules are easy to grasp, but mastering your spells and positioning will be the difference between survival and Game Over.
🔄 Death is Just a Reboot (Roguelite Progression) Failing is part of the protocol. If you fall in combat, you are rebooted to the beginning of the current sector. But you never start from scratch: keep all your core stats, gear upgrades, and unlocked spells. Grow stronger with every attempt.
