Master the Metal Gear REX boss battle in Metal Gear Solid. Learn its weak points, attack patterns, and strategies for both phases to emerge victorious.

Stats / Weaknesses:

  • Metal Gear REX — Weak point: Radome on left shoulder (Part I), Liquid's cockpit (Part II). Primary weapon: Stinger missiles.

Phases:

  1. Part I: Destroy the Radome
    - Target the radome plate on REX's left shoulder. Other parts are invulnerable.
    - DON'Ts:
    1. Don't stand still (missiles).
    2. Don't get too close (stomp attack).
    3. Only use Stinger missiles.
    4. Fire missiles rapidly; wait for the target box.
    - Strategy:
    - Use a chaff grenade at the start to confuse REX.
    - Hit the radome at least twice.
    - To avoid missiles, run directly towards REX.
    - To avoid machine gun, run away from REX.
    - Equip body armor if available.
    - After sufficient damage, a cutscene plays where Grey Fox intervenes, damaging REX and revealing Liquid. Fox is then injured by REX.
  2. Part II: Defeat Liquid
    - REX's mouth is open, revealing Liquid. REX will not move.
    - The basic DON'Ts from Part I still apply.
    - REX will use missiles, a machine gun, and a blue laser (if close).
    - Strategy:
    - Throw a Stun grenade to distract Liquid.
    - Use this time to hit Liquid in the cockpit twice with Stinger missiles.
    - This battle is similar to Part I.
Tips
  • Chaff grenades are highly effective for creating openings.
  • Stinger missiles are the only effective weapon.
  • Body armor can reduce damage taken.
  • Maintain distance to avoid stomps and machine gun fire.
  • Run towards REX to dodge its missiles.
  • Run away from REX to dodge its machine gun.
  • Use Stun grenades in Part II to create opportunities to attack Liquid.
