Halo: Combat Evolved Anniversary

Halo: Combat Evolved Anniversary Achievements

All According to Plan...

Kill all the enemies in the first encounter of “Truth and Reconciliation” without being detected.  

Immediately after getting off of the dropship, head to the cliffside toward the back of the canyon, but stand back far enough to avoid being seen. There are 2 shade turrets, 2 elites, 2 Jackals, and a handful of grunts (mostly asleep) Start by eliminating the Elites, than the Jackals, than the turrets. After that it's just a matter of taking out the grunts scattered around the canyon.

Note: Whatever you do, do not leave the cliff-side or the marines will move in and blow your cover. Do not stop hunting for enemies until the marines move on their own. That signifies that you're done.

Here's a video for further assistance:

I watched that video, and I have no idea what I'm doing wrong. It seems buggy, according a bunch of other people. I even killed them all with one shot, and as soon as I killed the last one, the enemies come around the corner.

Same thing for me. I even save a closer grunt for the last one and then they all come anyway. Maybe trying it not on legendary will help me, though I know my buddy already did it on legendary

This one was easy. Just stay back far enough and snipe them all. Then move around to the right side slowly and snipe the ones hidden on the left.

Here is a pro tip for this one if you are have troubled getting it. Turn on the Bandanna scull so you have unlimited ammo and through grenades over the big cliff wall, they wont detect you and you can kill almost all of them then if you need to you can go to the ledge to pick off any that are left.

Here is a pro tip, go back to school and learn some basic spelling, because
the majority of comments I've read, need to. On topic, this shit is bullshit,
I've killed everyone and as soon as I come around the corner the plasma turret
starts shooting at me, even on easy and creeping around the corner. Nice cheats.

Pro tip: If you're playing co-op, one person has to kill all of them, then you both get it

This one wasn't that bad. I found it to be a lot easier with the original graphics. Remember, the AI doesn't see all the extra stuff they added. You can only hide what was there in the original.

The grenade trick actually worked very well. All I had to do after chucking the grenades were sneak around the corner and shout a turret grunt.

@11 yeah, I was playing co-op and it didn't pop. Then my partner killed them all and it popped!
thanks for the info!!

FYI, when I did this, there was a Grunt hiding all the way on the right. I
walked the whole way to the right staying up on the ridge and I could here him.
Sure enough, at the end of that ridge he was standing right below it. I
plugged him and it popped.

oddly enough i got the easiest solution to this one..... go to the rocks at the side have boom grunt funeral and bandanna on and then make it rain in grenades.... yes i no grenades on steroids wouldnt be the best solution but i did it and got the chievie for it as well have fun i did

In case anyone, like me, was wondering. It doesn't matter if they are running around and on your radar. So long as you kill all of the enemies in the first area (which is between where you come in and the second shade turret) before they start firing at you then you will get the achievement.

When I'm about done the other marines always run in. No one is shooting at me but they still come into the area. How do i get rid of the support Marines?

I only get to take the shade turrets, 1 elite, 2 jackals and 2 grunts but then somehow the other elite somehow sees me

I think revert to last save doesn't work for this, because I did it a couple times (screwed up alot) and finally started restarting level rather then revert to last save, and it worked

Did it on easy. They can spot you they just can't fire their weapons. This one worked for me and was easy.

God. I can get the whole thing done, no shots fired towards me and no one spots me, but then the music picks up, Elites come around the corner, marines fire, etc...

I used the unlimited ammo skull and shot all of the guys I could see. Then I used my grenades to hit the remaining enemies I couldn't see. I hugged to the right of the tree until I took out all but one of the enemy. Every time I did move past the tree too early some grunt would almost always spot me. My last kill was the grunt in the second turret.

I'm only seeing one elite on my game and the three videos that people have said will help. Still can't get it. The first guy to come around the corner is elite. I have watched the videos a few time and unless I am really, really drunk this time I am only seeing people kill the one elite and then everyone else then it pops, WTF. I have done it just like the videos, shot for shot, at least 20 times.

and @10, WarzoneAchievements, trying to roll up in here and steal some members with that crap. Your video does not even work. I hope you are affiliated with otherwise that is shady. And you just put an ad of why not to go to your site.

Comment #35 by DrunkerDrunk
Sunday, September 23, 2012 @ 02:49:10 AM

I did it! There was only one Elite for sure. The guy I kept missing was a sleeping grunt. He was the closest from the start. I couldn't see him until I moved way up right and looked almost back to where I came from on the ground. It could just be a different spawn every time. If you are still having a lot of trouble then maybe go all the way to the dashboard or whatever they call it now, xbox home I guess, and try that fully reloaded one a few times. Good luck. I thought this one would be fun. Glad to have it behind me.

Turn on infinite ammo and grenades have larger explosions skulls and launch away just don't be seen OBVIOUSLY , you can avoid being seen by hanging around the first 3 rocks coming up the incline where you sneak around at the beginning of the level and shoot and grenade away , or watch a few you tube videos that show you where the harder enemies loiter close to the walls

If you are having trouble getting this, it is because you are not finding all the sleeping grunts. If you walk around the edge and turn ya TV up you will hear the grunts talking in their sleep. If it hasn't popped its because all the grunts are not dead when you drop down. This will pop AUTOMATICALLY when all the shots are fired and all are dead. Has nothing to do with dropping down off the ledge. Walk around the edge of the edge and you will find two grunts sleeping right under ya feet. Just be careful not to fall before the Achievement pops. YOU DO NOT HAVE TO KILL THE ONES AROUND THE CORNER!!!!
