HOW TO PLAY

  1. Press Start Guard to begin a 45-second defense shift.
  2. Move the shield between the left, center, and right lanes by tapping a lane or using 1 2 3 / the arrow keys.
  3. Block incoming threats before they reach the reactor core. Heavy shards deal 2 damage, and ricochet threats switch lanes halfway down.
  4. You score for every block, build combo bonus on clean streaks, and the run ends when time expires or all three cores fail.

ABOUT

Reactor Ward is a lane-defense arcade game about triage under pressure. You are not aiming or firing freely; instead, the challenge is reading which lane matters most right now and committing the shared shield before a weak core gets clipped. Your best blocked-threat count is saved on your device, and the strongest runs can enter the global TOP 20 leaderboard.
