About this game
Guard Protocol is a mech-based Vampire Survivors / Tower Defense hybrid where survival isn’t about winning, it’s about lasting as long as you can. Each wave grows stronger, every run ends in defeat, and the only question is: how long can you hold the line?
Customize your mech across every system, legs, body, engine, generator, weapons, and shoulder mounts, to define your own playstyle. Between runs, use resources earned from fallen enemies to unlock permanent global perks and upgrade your mech’s core components, expanding your tactical options for the next attempt.
Each run offers randomized perks and augments that shape your strategy on the fly: faster reloads, explosive shells, piercing rounds, electrical damage, and more. The right combination can turn your mech into a walking fortress, but no build lasts forever.
Battle through endless waves of enemies, mini-missions, and boss encounters that escalate with each cycle. Every defeat makes you stronger, pushing you to survive just one more wave.
Key Features:
Deep mech customization across multiple systems
Permanent global perks for evolving long-term strategy
Randomized perks for unique builds each run
Endless wave-based survival with escalating challenge
Boss encounters and mini-missions that break the flow
Meaningful progression through cash and core rewards
