I go through level 1 in Halo CE (Steam) until you meet Captain Keyes, kill the two grunts, and then kill him.

When the invincible Marines come out of the secret door, the door behind it won't open, so I can't get the achievement. Has it been removed?

The achievement has not been removed, it might just be a bit tricky to get:

  1. Start “The Pillar of Autumn” on the Legendary difficulty (you must be playing alone).
  2. After you gain control of the Master Chief, walk toward the canisters behind you.
  3. Crouch jump on top of the yellow canister and then jump off.
  4. Move through the level as normal until you get to the bridge of the Autumn.
  5. Trigger the cinematic by walking towards Captain Keyes.
  6. After the cinematic, he will hand you a pistol. Continue forward, pick up ammo, kill the 3 grunts, and return to Keyes.
  7. Shoot him in the head to kill him. Doing this will make 3 invincible troops come out of a secret room that was previously locked.
  8. You’ll have to lure them away from the door, by sitting in the middle of the room, and then quickly make a dash for the newly opened door without being killed.
  9. Once inside, you can look at the ceiling above and notice the “Megg” Easter Egg using your flashlight!

Remember dear, this can take a few tries but you can use your checkpoint and still get the achievement. Also, it’s not required to kill Captain Keyes, anyone in the room works. The other NPCs don’t always die, Keyes is guaranteed for the room to open.

Let me know if it works for you.

  • Ohhh I did everything except the canister thing thank you so much I'll try that and tell if it works :). Commented Feb 14 at 13:30
