Sentry Guide — Strategy & Tips


Phase 1 — “Warm-up”

  1. Force Distribution

    • Split into 5 equal groups — one per platform (zone).
  2. Positioning

    • Keep distance between players.
    • No one should stand in front of the boss.
  3. Laser Mechanic

    • The boss periodically fires a laser at a random player.
    • The farther apart the legions stand, the less chance of hitting neighbors.
  4. Preparation for Movement

    • By the end of the phase, be ready to quickly switch platforms — this is important for the next stage.

Phase 2 — “Circle of Invulnerability”

The boss moves to the center of the arena, becomes invulnerable, and cyclically activates six abilities. During these mechanics, the platforms spread apart, and the portals between them are the key survival tool.

Battle Cycle

  1. Phase 1 — deal damage, keep distance.

  2. Phase 2 — boss is invulnerable, play the “portal mini-game,” survive.

  3. After Phase 2 ends, everything returns to Phase 1. Cycle repeats until victory.

Quick Tips

  • Pillars = priority: the faster the pillars are destroyed, the less chaos with lasers.

Stay organized, learn to “read” the portals — and the Mech Guardian will fall without heavy losses!
