How to unlock the The Ol' One-Two achievement

    When you first play the Clash in the Clouds DLC you'll have to pick up the first 4 vigors on the table to your left |FREE SAMPLES|, then when playing some of the waves you'll have to save up money to buy the rest of the Vigors. Once you start to combo on a kill you'll see what you combo pop up in white and how much money you've earned.

    Total of 8 different combination moves are:

    • Possession and Shock Jockey
    • Possession and Devil's Kiss
    • Devil's Kiss and Charge
    • Murder of Crows and Devil's Kiss
    • Murder of Crows and Shock Jockey
    • Bucking Bronco and Devil's Kiss
    • Bucking Bronco and Charge
    • Undertow and Shock Jockey


    Load up Raven's Dome for the last couple of kills you need done and keep doing Wave 1 or Wave 2 if needed.

    For Possession + Shock Jockey you'll have to Possess the enemy first then shock them repeatedly until the Possessed enemy gets a kill while being shocked. The Possessed Enemy HAS TO GET THE KILL, NOT killing the enemy with Possession and Shock Jockey.

    For Possession + Devil's Kiss you'll have to Possess the enemy first then Devil's Kiss setting them on fire, the Possed enemy HAS to get the kill while being on Fire. This is a bit tricky since you could kill the Possessed Person with Fire Damage or it delays the kill. The Possessed person has to get the kill.

    You might wanna upgrade the vigors or salt infusion or at least damage the enemies then use it. It's a cumulative achievement so you can come back to it or do it on any waves. (Also what helped me was putting a check mark or opening a word document on the ones I already did.)

    Keep trying every combination again if it didn't unlock. I strongly suggest writing them down or a word document to keep track and to tally off which ones are done. If for some reason it's not unlocking come back to it once your done with ALL the achievements and delete your save and start a new save make sure you cancel the upload save when you start the game. But I really recommend you do this if it's your last hope on 100% this game.

    thatNoseyParkerI'm scouring info over the internet trying to get mine - stuck at 7/8 so I can't use the tracker to double check if one counted.

    Does anybody have a list of point values that are given with the combo which mean you got the kill the with combo rather than just damage? E.g. According to the 360 version comments, Possession and Shock Jockey give a 45 (55 in vid) point combo if you got the kill

    Edit some ideas of lookout helpers - on crow combos, having damage over time bonus, and for possession having friend kill bonus (the latter not guaranteeing the combo in effect for the kill, but one requirement checker I guess)

    Edit 2: POPPED! So firstly, crow and shock didn't save for me, I did it again and got my 7/8 notification again, not sure on the save point. Then, on the next wave, continuing the cycle (for the millionth time), I got it on Bronco with Devils Kiss.

    In case anyone else is missing this too, I did it on Raven Dome, Wave 2, fully upgraded carbine. Shot a male soldier twice, Bronco'ed him into the air, then threw my DK directly under him, killing him with the explosion rather than DOT (I think). Both vigors were also fully upgraded.

    Nevertheless great guide.

    CodeMonkeysGuyDefinitely seems finicky about registering these combos internally. Bucking Bronco and Charge was the 4th one I did, and I remember it popping up as 4/8 in-game and registering on the achievement stats. But that was the one I had to re-do to get the achievement to register 8/8.

    SanglamoreNothing is working for me. 7/8. Went through the list many many times. Once in a while I get a pop-up of 4/8 and that's it.

    EDIT: Got it after I started a new save. Had to repeat everything many times, still. But it worked.

    I MulligaN IWeakening the target before hand, seems to be key for this. I recommend just using the burst-gun and shoot at the your target once before trying your combo.

    DJ Ghost133I had problem because it didn't pop for me after completing the list it was stuck on 6/8 trick was in using alternative fire(holding your plasmid button) in possesion then shock jockey and same with devil's kiss

    EmperorBelloJust something to remember guys... KILLING BLOWS I had done all of these vigors over and over again and it turned out that I had not actually KILLED someone with crows and shock jockey together. Its not enough to get the bonus you need to KILL someone!

    sonnyliston1DJ Ghosts tip worked like a charm.

    Grimm TimPossession and Devil’s Kiss is absurd. After they’re possessed, you hit them with DK and they are on fire for 3 seconds, 2 seconds of which they are in a staggering animation. So frustrating.

    deathbyfishk87I had the same issue as @EmperorBello, thanks for the tip 😁
