About OVERHEAT PROTOCOL

ONE RIFLE. RISING PRESSURE.

OVERHEAT PROTOCOL is a fast-paced arena FPS built around intense survival runs. Enter the arena with one rifle, stay mobile, and cut through escalating waves of hostile machines before their numbers close every escape route.

Keep moving. Keep firing. Build faster than the arena escalates.

SHAPE THE WEAPON DURING THE RUN

Every level presents a new upgrade choice. Push raw damage, fire rate, precision, piercing, critical hits, or survivability to reshape the rifle's damage, handling, and projectile behavior over the course of the run.

Choose an elemental protocol and specialize into Lightning, Explosion, or Shatter. Arc damage through groups, detonate packed enemies, or break formations with cascading fragments.

OUTLAST THE MACHINE SWARM

As enemy numbers rise, positioning becomes increasingly important. Read the arena, control the crowd, protect your escape routes, and decide whether your next upgrade should increase power, control, or survival.

When the run ends, review your survival time, kills, level, and collected XP—then return with a different build and push your personal best further.

  • Fast first-person arena combat
  • Run-based level-up card drafting
  • Lightning, Explosion, and Shatter specializations
  • Escalating wave pressure with less room to breathe
  • Survival-time and personal-best tracking
