Idle Protocol
SteamAbout Idle Protocol
Welcome to the Mainframe Idle Protocol is a minimalist sci-fi tower defense / idle incremental game where tactical loadouts and economy management meet raw, exponential firepower. Set in a dark, neon-lit digital void, your goal is simple: manage a central CPU core and defend against an endless swarm of geometric anomalies. Dual-Core Tactical Combat Forget building complicated mazes. In Idle Protocol, you equip exactly 2 active Nodes (Towers) to face the swarm. Choose from 5 distinct weapons, including:
•
Kernel: A balanced central core that focuses on consistent damage and devastating critical strikes.
•
Surge: A high-fire rate node that unleashes devastating Chain Lightning.
•
Solaris: A heavy sniper that applies intense Thermal/Burn damage.
•
Trojan: A viral node that applies Damage over Time through Malware.
•
Cluster: An unstable containment unit focusing on Explosion/AoE damage.
Deep Meta-ProgressionHit an economic wall? Perform a System Reboot to prestige and earn Cycles. Spend your Cycles in the BIOS—a massive Hexagonal Grid Layout skill tree—to unlock game-changing Ultimate abilities like "Infinite Loop" or "Supernova". Defeating Bosses also grants Upgrade Points (Chips) for the Circuit tab to further optimize your build.
The True End Game: Quarantine Protocols This isn't just an endless grind. Reach Wave 500 to unlock the true endgame: Quarantine Protocols. Initiate a run with up to 5 brutal modifiers—like the No-Click Protocol or Monocore restrictions—to prove your architectural mastery and unlock exclusive Alternate Skins for your nodes.
