How to unlock the He’s Unstoppable! achievement

    This is a straightforward achievement, but if you're having trouble, here's the easy way:

    Play campaign split-screen (with a second controller). You'll need to press "Y" in the Campaign select screen to change your network to console-only.

    Have your second controller run through a level. If you die, you'll spawn on your main profile, which won't take any damage.

    That's it.

    If you're going to do something so boring, you might as well stack this with the Pillar of Autumn Legendary achievements (don't pick up overshield or health packs on main profile) while using Boom (bigger explosions), Bandanna (infinite ammo), and Grunt Funeral (Grunts explode upon death—preorder bonus, if you have it) for the three skull achievement. You'll also get your three co-op achievements. (That's seven achievements with 185G, for those counting.) Honestly, Legendary is a piece of cake with infinite grenades and massive explosions.

    TeamBonesCOI like this technique, but it doesn’t work on Library, at least for me. There was a door the Monitor wouldn’t open until I got both players there. Then the Monitor cut off our escape and a mass of Flood came in, and I eventually took damage.

    Important notes for getting this achievement after several annoying playthroughs.

    Firstly, medpacks do not count, if you hurt yourself and heal back to 100% your achievement will not unlock.
    Secondly, if you hurt yourself and reset to last save or restart mission, it still will not count.

    Basically, if you hurt your health in any way, you will need to quit and restart the mission otherwise the achievement will not unlock.

    All these were discovered painfully after nearly 8 playthroughs of Pillar of Autumn on Heroic

    A tip though. Every few checkpoints, save & quit then reload. Now if you die, go back to your dashboard, reload the game and resume. All is forgiven and you're back where you were at the last time you saved & quit. You may need to run through one or two more checkpoints again, but it's easier then repeating the whole level.


    PS: thinking about it, the number of times Halo games have had this exploit, you' think they'd have solved it by Reach now, huh?

    THE Wheelman 87Given the way the Halo engines track and save game progress I don't think they CAN fix it without changes to the game engine.

    Shadow XBLThis is a great tip, the dashboarding. Thanks!

    This one is not so bad you can do it with other achievements like not picking up med packs or using over shields on the Pillar of Autumn. I did this one with 3 skulls active (bandanna, grunt birthday part, famine)which did help. I would suggest having bandanna skull as you can chuck loads of nades and hide.

    If you feel that is too much of a challenge load Pillar of Autumn on heroic and focus on not taking damage. with bandanna feel free to chuck grenades a plenty just stand well enough back, whenever you see a life pod point there are over shields inside, if you feel comfortable don't take them if not then take them and make it easier.

    Apart from that its fairly simple just take your time and don't do anything risky.

    This can be done in coop.

    soliunasmI'd like to add that you might not be able to get this if you Restart from Previous Save. I managed to get the two Legendary achievements on Pillar of Autumn just fine and was going for this as well, but apparently I didn't get it even though I didn't take health damage(I'd always restart from last save or die if I did) so be careful.

    soliunasmAlright, it seems that if you get hit at all(Even if you die or revert save) it won't credit it to you. I just did a second run(On heroic) where I got hit and rather than reverting to my last save I suicided and still didn't get it. On my third try I beat Pillar of Autumn on Heroic without getting my shield down at all and I got it at the end, so if you aren't getting it, it might be because you took health damage and reverted to a checkpoint or died after taking damage.

    MathGuy42You can get this if you go out to Dashboard. I went through carefully, using Save and Quit periodically. I did take health damage a couple times, but instead of Save and Quit, I went out to the Dashboard. I could then Resume from the last place I did Save and Quit.
