Halo 3: ODST

Halo 3: ODST Achievements


Find all Audio Logs, alone or with another ODST.   

Note: This achievement is made much easier on Solo.

Audio Logs located in Mombassa Streets: 29
Audio Logs located in Data Hive: 1

Click here for a map of New Mombassa that details the locations of the 29 Audio Logs. Once you have the first 29, you'll have to play Data Hive and proceed through the level with the security guard.

Once you enter the area where he tells you to stay put and look out for hostiles, ignore him and follow him into the room. You'll find the 30th Audio Log on the wall to the left.

Be careful though, once you pick it up, the security guard will say that you know too much and turn hostile.


  • Turn on your VISR and you'll be able to see the Audio Logs much easier; they are outlined with a yellow border.
  • Sirens, telephones and the voice of the Superintendent indicate that an Audio Log is nearby.
  • If you replay a level on co-op, you will lose all of your Audio Logs. This is why you should play on Solo.

A pain to get, but well worth it. The last one is hard to get seeing as though it's on the last level in an icey room, check YouTube for videos on that one...

OK a friend and I have just found 29 of the audio logs, can we quit out and load up the last level and play 2gether to get the last audio log, or will it reset our logs

i havnt done this but im about to, im guessing you cant chrisarcade, because when you save and quit and choose a new level, it basicly asks you "are you sure you want to quit, you will lose your current progress"..something like that.

Searching Is made a lot easier if you find the supply caches and use the mongoose to get around.

I'm a little irritated with this right now. I've got 28 out of the 29 on Mombassa Streets. I cannot for the life of me find the last one. I've looked at the maps, went to all the locations, and couldn't find it anywhere. Is there a way to reset these damn logs and just start fresh? Or should I just invite a buddy over and do some co-op to get this?

Working on this just now with two other players, we went around and picked up all the logs in Mombassa, we went to the train station to try and get to Data Hive, but it seems we have to play all campaign missions from their locations to get to Data Hive, is this correct? Gonna try and knock that off tomorrow, if that is the case.

i missed one or two in the main levels, now i have to roam the streets searching for the last ones.. damn!

All it takes for this achievement is a good guide and some patience. I got half of the logs just playing the game. The other half I used a guide, and the last one is on Data Hive. At one point, in a room that looks frozen and is chock full of brutes, the police friend you make will break away. Just follow him to the log, but you'll have to fight the police buddy. He's a pushover though.

@GAThrawn, that map was the best one that I have ever come across! It was nice to be able to check off the ones that I already found without printing a map out. I tried that once before, and it was all black, making the map unreadable. I started from Uplift Reserve and worked all the way to the one that I was missing (the 29th one). Thanks for posting that!

To the people that has trouble finding the last audiolog, you have to play the campaign mission Data Hive. The audiolog is somewhere in the icy room so be sure to have your VISR on.

Your welcome

Comment #20 by Dramatic Unknown
Tuesday, August 30, 2011 @ 04:40:32 PM

Oh yeah and one more thing. You MUST have all 29 audio logs to get the last one in Data Hive, otherwise you wont be able to see it, even in VISR mode. Ill repeat, you have to search for ALL 29 that are all in New Mombasa, and the last 1 in Data Hive.

Youre welcome...again, and enjoi your 75G.

Really easy 75G (125G if you count the other audio log achievements). Takes abou 30-45 mins if you start from 0.

For people who are having trouble finding the 29th audio log on the New Mombasa Streets: Go into your VISR Database and go to the section where you can listen to the logs. Count how many you have (there are 9 "circles", each containing about 3 to 4 logs). Sometimes, when you obtain the 29th log, the progress bar will pop up and say you have only found the 28th log. This is NOT for sure, but it happened to me and I have noticed a lot of people having a similar problem. If it doesn't work, I don't know what to say. Hope this helps.

I had 1 left and luckily I found it quick... The map was accurate on where the file was, but not where the security door was to access it. Hopefully this is the one some of you are missing as well. If you look at the map it ALMOST looks like it could be divided into to parts. Where the divider ends, directly to the left there is a file and the security door is located near the red barrier.

If you find yourself looking for a file around where you see a big "8", that's where I found it. In the photo of the audio file there are also two engineer's and the audio file is a phonebooth.

This should fix audio log stuck problem

If you ended campaign, go to Main Menu ==> Campaign Lobby:
1. Change network to "My Xbox"
2. Choose mission "Mombasa Streets"
3. No Skulls!
4. No Scoring!
5. Difficulty "Normal"
Start the game. Go through all location using this map:

If you are having trouble finding the last audio log like I was then you need to know it is not in the streets but in the lv. Data Hive.

Comment #46 by nselvo
Saturday, September 21, 2013 @ 08:28:13 PM

In case anyone was unsure, you DO NOT have to devote another playthrough to audio logs if you missed some. Beat the game once (might be a good idea not to pick up any audio logs during the playthrough unless you remember which locations you got). Then from the main menu select 'campaign' then 'mission' then 'replay mission'. Select 'Mombasa Streets' at the bottom of the list. This will load the open world map with all doors unlocked. All audio logs will be available on the map too. (You can also kill the 10 engineers in this one mission for the Naughty Naughty achievement.) I'd set the difficulty on normal just to be sure you get it since easy locks some achievements in other Halo games. As others have said, solo is much easier for this because it doesn't reset any logs you've gotten befor

Comment #47 by nselvo
Saturday, September 21, 2013 @ 08:31:24 PM

e. If you use the following guide and do exactly what I said, you should be able to knock this out in 30-45 minutes. I got the audio log achievements and Naughty Naughty doing this so I know it works.

Comment #48 by Browknee
Monday, November 25, 2013 @ 02:48:49 AM

@47 . In your guide the picture describing audiolog #21. Is actually a picture of audiolog #27. The location of #21 on the map is correct just the picture is wrong. For anyone following the guide above, keep that in mind.

audiolog #21 is a massive kiosk looking thing.

Sunday, September 07, 2014 @ 03:51:25 AM

I'm having the same,problem as many other people. I'm sure that I've collected all 29 logs, but the game only registers 28. If anyone can help, or if there's a way to contact Microsoft in order to get the achievement, please let me know.

Comment #53 by SPECTRELIGHT
Friday, April 24, 2015 @ 04:30:38 AM

Truly, this is an EASY one, once you have all the levels unlocked. (Play through on easy and get the good samaritan achievement)
Replay Mombasa Streets as many have stated above. Go to a supply cache and get a mongoose.
Load the map in this link and go through the Videos one by one.
Make a small checklist of 1-29. Check off the ones you have and you'll find the one(s) you're missing in no time.
It took me less than an hour to find them all.

Comment #54 by Gilbert Prime
Tuesday, June 28, 2016 @ 04:11:39 AM

Either resist the urge to start collecting the audio logs until you've unlocked all the street areas or keep really good notes of which ones you've clicked on. Otherwise it is a pain to backtrack to see which ones you've missed.
