Halo ODST: Trying to get to Mission 10!!!

I’m new to this game, but I think I might have a problem. I’m playing ODST in single player mode and on Legendary. I played through level 9, where you protect the Engineer from attacks along the Coastal Highway and then from multiple waves of attackers while waiting for a Phantom to pick you up, if successful. I was successful and was picked up by the Phantom. After the cinematic and credits rolled, I was awarded the achievements for finishing the game on “Normal”, “Heroic”, and “Legendary”. After that, the game continues and drops me off right at the beginning of Mission 9 again! From what I understand, Mission 10 should fire up on its own without me having to do anything. What did I miss or where did I go wrong? I just want to get to Mission 10 so I can finish the game and get my last two achievements, “Super Sleuth”, for finding the final clue, and “Audiophile”, for finding all audio logs. Any help with this matter would be greatly appreciated. Thank you.

This is really only 9 missions and if you completed Coastal Highway, you finished the game.

Yea there really isn’t a “Mission 10”. Halo likes to count intros and epilogues as missions for some reason, even if there is no gameplay what-so-ever.

Example: Halo 2’s first mission is called Armory / The Heretic. You only do the shield and view calibration and watch the cutscenes. That’s it. Congrats you just beat a mission woohoo!

If you have finished Coastal Highway, then you have finished the entire game. There is no mission 10.

In order to unlock the Super Sleuth achievement, you MUST start at Prepare to Drop (the very beginning of the game), and then find each of the 6 clues (items that launch flashback missions upon their inspection) and play their corresponding missions. This must be done in the proper order as well. This will unlock after you find the sixth item if you have done it correctly.

  1. Recon Helmet - Tayari Plaza
  2. Optics Package - Uplift Reserve
  3. Gauss Turret - Kizingo Boulevard
  4. Remote Detonator - ONI Alpha Site
  5. Bent Sniper Rifle - NMPD Headquarters
  6. Biofoam Container - Kikowani Station

If you do any action that “resets your campaign data”, which includes changing difficulty, replaying a mission, or turning on/off skulls, your progress towards this achievement will be reset and then you cannot finish it without going back to Prepare to Drop. Also if you need to quit the game for any reason, make sure you use the quit to main menu option. Going straight back to the Xbox dashboard will also void the achievement and mean you have to start again.

In regards to the Audiophile achievement, you first have to find all 29 of the other audio logs. Then during the Data Hive mission, simply keep following the man who you escort at the beginning of the mission. He will eventually tell you to wait for him while he goes to sort something out. Keep following him again into a room and he will get mad and try to kill you. Kill him and you will find the last audio log on a wall near the corner of the room.

That’s it there is no mission 10
