I started this from Rally Point Bravo and the marine(s) weren't there but I still got the achievement for going to that location

[@Phy6ics1351]

I'm doing everything that he has said, but it wont pop up for me
Edit: It popped up 8 days later

[@IdiotWithiPhone]

44 MCC achievements to go! Thanks for the guides!

[@RandomDude4268]

How did you par score

[@MasterBeChiefing]

@@RandomDude4268 par score was BITCH on exodus! I just did it today lol

[@JESUS.IS.GOD.777]

Bro I have gotten almost all of the achievements thanks to you!

[@KirbyTheKirb]

So sad that there aren't any marines there, the achievement makes no sense if there aren't any marines. I wonder if they get removed during a load zone or something, perhaps the intended way is to do it some other way. Who knows, just wish there was something to see once you get there.

[@ixKiLLxZ0MBi3Z]

Originally and the falcon fly through you pass by the same building that you go stand on right there for the achievement and when you’re passing by there’s a bunch of brutes especially one that’s a chieftain with a hammer running after a bunch of Marines and I think the actual point behind the achievement is to go and see the Marines that aren’t there anymore they were apparently killed maybe that’s what it is

[@NotALotOfColonial_SpaghettiToG]

Did this again and found there's another "RETURN TO BATTLEFIELD" barrier that stops you from going to where that pelican very first starts with those marines getting gravity hammer'd while being chased by grunts + the brute with a plasma repeater? that kills you almost instantly on LASO

[@AlanagilityUK]

Just did this. Actually you don’t have to do so much jumping at beginning. Once in water just walk staying close to cliff. Eventually you reemerge on beach 😊

[@antonybr1]

Now with acrofobia skull is super easy

[@NotALotOfColonial_SpaghettiToG]

Bruh i cant even get past the second jump, I keep reaching a killzone when trying to hide in the water. who the fuck decided to make this an achievement

[@NotALotOfColonial_SpaghettiToG]

My salt has ended, actually really like this achievement now.

[@grahamhill676]

​@@NotALotOfColonial_SpaghettiToG Character development. Love it

[@Damitsall]

This isnt working for me, when I try to get to that first ledge there is an invisible barrier not letting me go high enough to get on top of it.

[@odstarmor557]

When you get high enough let go of the equipment button to let the jetpack recharge a bit then you can go higher.

[@AlanagilityUK]

Just walk in the water

[@Zetpherious]

I had this issue too doing the datapads. Max out the jetpack height then keep tapping it, it will keep boosting you higher

[@der_vur]

Did it with acrophobia skull after many deaths with jetpack

[@TheWeedyBird]

Wicked! Appreciate it man

[@Finger112]

You can walk along the beach as well once you jetpack over there.

[@CsquaredaapGaming]

I did find a banshee out there but nothing else...... No achievement or anything and the worst part is that u cant even fly the banshee

[@shanemiller6074]

This worked for me on Xbox no marines there but the achievement was still given

[@laserdragonflying966]

i hate it when u say 'were just going to jetpack over here', first time i always get real close and then spend a couple hours with an increasingly shorter run until i suicide by reloading my gun. Great gides though, can we have the bloopers on the end to make me feel better?

[@marclupinaccijr3235]

For some reason I've tried this three times and no achievement

[@Ares_gaming_117]

Wish they didnt have invise barriers id love to explore new alexandria with acro skull

[@theanimeman97]

When will you be hitting the Par Score/Par Times for all the missions? Based off you're current rate, it seems you're probably saving those for last.

[@SKYGAZE]

For Par Scores, I reccomened playing Legendary; I got most of that mine done.

[@HaloCompletionist]

Yeah, getting all the easter eggs and LASO out of the way first. Probably starting up either par times or scores in the middle of this upcoming week.

[@davidkapusta2301]

Did this with my brother achievment popped for him but not for me. What should i do?

[@Dippa1991]

Cry

[@JondarKorric]

achievement flat out refuses to work for me, same with the "kill a BOB" achievement

[@spartanbhagwa7066]

How come you have 70 rounds in your DMR?

[@hajimenagumo2199]

if you start from rally point charlie youll get 90 rounds

[@DavidbarZeus1]

@@hajimenagumo2199 Odd, most I've ever been able to carry is 60

[@DittoBlast]

Such a stupid achievement

[@about3penguins]

Why would you use a controller in MCC?

[@dasolemnvizitah4473]

Because it's fun

[@twi.]

This is on xbox.

[@Benjamin-ey9jg]

Halo was built for a controller

[@nextao6384]

Feels wrong to use mouse and keyboard on Halo.

[@techissus7449]

Because it's been proven to be a godsend on MCC pc
