Learn about Sentinels, 343 Guilty Spark's guards, and how to defeat them in Halo: The Master Chief Collection using plasma weapons.

Walkthrough
  1. 1
    Sentinels are initially allies in The Library, helping you fight the Flood with their lasers.
  2. 2
    After The Library, your relationship with the monitor 343 Guilty Spark sours, turning Sentinels into enemies.
  3. 3
    They will attack you with lasers; a group can quickly deplete your shields and health.
Tips
  • A charged Plasma Pistol shot is the most effective way to destroy a Sentinel in one hit.
  • The rapid fire from a Plasma Pistol or Plasma Rifle can also take down a Sentinel quickly.
  • Place a Plasma Grenade in a Sentinel's path; they are sensitive to close-up explosions.
  • If you stick a Plasma Grenade onto one Sentinel, it can destroy a group if they are close together.
