Halo 3: ODST

Halo 3: ODST Achievements

Super Sleuth

Find the final clue unraveling the mystery, alone or with another ODST.   

The final clue you'll find is a hole in a wall. Once you find it, walk up to it and press to study it. This will trigger a flashback and the mission: Data Hive.

Note: Some people see to be having problems with the Junior Detective, Gumshoe, and Super Sleuth achievements. See below for a list of solutions.

- You cannot replay a level while in the middle of a campaign.
- You cannot go from playing a campaign solo to co-op or co-op to solo.
- If you're playing co-op, the person that studies the first clue should study all of the clues.

List of clues in order of appearance:

  • Dare's Recon Helmet
  • Drone optics
  • Gauss Turret
  • Remote detonator
  • Bent Sniper Rifle
  • Bio-foam canister
  • Hole in a wall

This must be done starting with the drop mission and done in one go without quiting or else it doesn't work.

popped for me after finding the biofoam canister and watching the cutscene (just before kikowani station). i did not do the whole game in one sitting, but i did do each mission in one sitting.

Exactly the same as #4... each mission in one sitting, popped at the start of Kikowani Station.

I think you need to find the "clues" in the order that the map says.

Got the achievement. You MUST PLAY through the CAMPAIGN (without saving and quitting) and it WILL UNLOCK once the cutscene ends after INSPECTING the BIOFOAM CANNISTER.
