How to unlock the I promise to kill you last achievement in Army of Two - Definitive Guide
(You're other videos work for me so I don't think its on my end.)
Basically, equip two weapons: the MGL-MK X grenade launcher for your primary and the M107 Light 50 sniper rifle for your special. It would help to have them "de-pimped" as it were, it will attract less agro to you. It probably doesn't matter, but it doesn't hurt either.
Blast him with the grenade launcher until he falls to your level. It should take you around 5-8 blasts, depending on how accurately you hit him. Throughout this whole process, don't worry about getting hit, just focus on hitting him - you'll get through it without dying, don't worry.
When he drops down to your level, your going to want to quickly finish him off with some well placed headshots using the sniper rifle. It won't work as well if they aren't headshots. Try to hit him the first time to get him to hunch over, then keep blasting. I found this to be a little challenging, but stick with it. Also, if you go right, like in the video, and he keeps going into cover, try switching over to the left side, it sometimes makes it easier.
Hope this helps!
The difficult part of this achievement is getting Dalton's cowardly ass off that catwalk overhead, and that's where your trusty SVD will assist you. Three headshots will trigger the cutscene where he falls down, and you have leave to finish him off however you please at this point because you still have 30 seconds on the clock. I personally opted to headshot him three more times (which is enough to end the fight), but you have plenty of time to just unload a machine gun in his face if you're so inclined.
I tried to do this the other ways but then tried this way and it worked best
Getting Dalton down from the catwalk with MGL is a breeze. The hard part was landing clean hits on him with a sniper. At first I went right many times, like in the video = no luck, than I went left many times = no luck either. I was like WTF!? can't properly hit the guy! And than all of the sudden game magically decided to freeze Dalton in one place, he hasn't moved an inch after falling from catwalk and I've got my perfect 3 shots.
If you struggle with this give it few tries and maybe game will cut you some slack.
There are a lot of great guides already posted, but with the online having been shut down some of the solutions involving a partner, instead of an AI, may not be suitable for everyone unless they have a local teammate. This solution is for those that have an AI partner. While this could also be used for a local teammate I believe the other solutions are probably more suitable in that circumstance.
In all honesty, I am by no means a marksman so, personally, I had some difficulties using the sniper methods. Either Dalton was too quick to move behind cover, or I just completely missed the headshots. I tried all the methods above that could be done with an AI partner, and the best way I found to do this achievement was without the sniper.
I equipped myself with the FIM92 Stinger and PKM. Both are fully upgraded. After the cut scene I immediately pulled the stinger out and fired 2 shots at Dalton. That should immediately take you to the next cut scene. Afterwards I pulled out the PKM and ran around the left side towards Dalton who should be directly across from you. I then started to empty my clips on Dalton. I did my best to headshot him the majority of the time since that does the most damage, and that should be the end of mission.
Just as an extra note I also found that instead of pulling out the PKM right away after the second cut scene I would run around the left as usual while reloading the stinger. Once I had a clear view I would use my last shot with the stinger on Dalton before using the PKM for the rest of his health. Some may find that last shot with the stinger to help out a bit more instead of immediately using the PKM. I’ve done both so either method should work.
I hope this helps those stuck with the useless AI!
You must kill Dalton in under 40 seconds. Easiest done on recruit in co-op.
Once the fight with Dalton starts have both ppl use PMK's or if you can't shoot well enough with it then use AK-47's. You must knock him off the bridge within 10-12 seconds max, if you have to reload or if he walks too far to the right, it has taken you to long. Once you do this and he is knocked off, immediatley after the cutscene take out your sniper, use the M107, and have both people instantly start firing headshots at Dalton, he should be across the room, once the cutscene is done he will directly across the room from you. It might help to take 2-3 steps to the left to get a clearer shot. If you both hit him with 2-3 headshots you should make it in under 40 seconds. The achievement should pop up about 2 seconds after he dies so you will know.
Now this is a very difficult achievement, you won't get it quickly. you and a partner will have to practice this many times. The most key part is being able to knock Dalton off the catwalk in about 10 seconds, 12 max!! Try to get him before he goes past the first bend of the catwalk. Just open fire right away with a PMK or Ak-47, me and my friend used Ak-47's but PMK does more damage but is less accurate. To get the headshots you will need to get lucky. Sometimes Dalton will run and hide, but right when the cutscene ends you will have a few seconds where he is out in the open shooting at you and if you get lucky he might even stop to reload before running to cover. You have to have your hand on the LB button in the cutscene getting ready to swtich to sniper. Once that scene ends run 2-3 steps to the left if you need to and instantly line up a few headshots. Like I said I got about 3 off on him and my friend got about 2-3. The headshots are key.
