A user named Jedidiah mentioned in the comments "I got the "Sounds Familiar" achievement not on the multiplayer map, but kind of randomly while playing Tsavo Highway on Normal. After overhearing the brute chatter from the second downed phantom, I got the achievement. Maybe there's a chance something special plays a little while after the regular chatter, but by the time I got the achievement out of nowhere I was too far away to hear anything."

Did Tsavo Highway all on foot and didn't get the cheevo. What a crock of bull****.

MCBTVHALO 22 Aug, 2023 @ 7:49pm

Same here with the Phantom Hunter achievement. I've tried multiple methods, including doing the same on my Xbox and it still has yet to pop. On my Career page, it shows I have 2/3 Phantoms destroyed which is confusing, but it won't count any of the others I destroy on the Covenant!

StormDragonZero 29 Jul, 2023 @ 3:52pm

Phantom Hunter on The Covenant does not want to unlock for me. I've tried on Easy & Normal. I've tried starting from Alpha & Beta waypoints. I've tried killing myself after destroying the first Phantom and repeating 6-7 times. I've tried restarting 6-7 times after each kill. I've tried destroying the two friendly Phantoms that come in once reaching the structure. I'm probably hitting around 40-45 multiple attempts of all kinds listed and still nothing.

I am not sure what I have to do to get credit for it. I've obtained loads of other achievements completely fine, including Flipyap. Anyone else having issues?

This is really helpful ty

Garakuof 18 Sep, 2020 @ 11:17pm

Is the LASO achievement bugged for anyone else? I've completed the entire playlist but the achievement wont pop on steam, it shows up in the career tab though.

Foozo 22 Jul, 2020 @ 7:31am

with the "Mind the Gap" achievement, its super easy to get if you turn on the acrophobia skull, drive out the first 2 warthogs, fly to pretty much near the end of the map, the cave with 2 choppers on the other side, then fly back to your first 2 warthogs, you have just despawned every enemy in your way of the achievement, make sure you pick up the first grav lift and flip over the warthogs or else they may despawn too

Foozo 21 Jul, 2020 @ 10:06pm

@soup i think you are correct, i just flew through the map with the Acrophobia skull on and the achievement popped, Cant use any land mounted turrets, thats the only thing i can think of that i used last time compared to this one

Foozo 21 Jul, 2020 @ 9:37pm

Thanks soup ill give that a shot right now, I dont think i used any turrets but i could be wrong,

A tip for the sandbox skull @Ginger Giraffe, Place 6 mines with a 10s respawn timer and spawn them in a big pile until everything in the map dissapears, Then you can run out and grab the skull, you just de-spawned the guardians !
