The last achievement

[GR1MA550]

Hi guys, can anybody help me with the last one achievement? Its about to kill someone with every weapon in the game. Im allready frustrated, cos Im sure that Ive used all the guns and still have not this last achievement. So, can I try make it this way? - will find, in which cases are different weapons, load the case, use the gun, exit the case, load another case etc... Or I have to finish the every case with the guns? Is there any chance to check, which gun I missed?

If you are having trouble with the Rosco and Friends acheivment then the problem is usually with two guns. The BAR Assualt Rifle can only be found in "A Different Kind of War" in both gun rooms, The gun that is always missed is in "Armed and Dangerous", during the bank shootout simply press G to drop your shotgun and use Cole's service pistol, The only time it is featured in the game is during this mission. That should help.

I did those too, I even used the flamethrower, still achievement not unlocking, why would that be ?

[GR1MA550]

I already have all the achievements. My problem was, that I was killed after flamethrower using. You have to survive after killing with the last weapon, than the Achievement will pop up.

I did the walkthrough 3 times over and over and it finally unlocked. dont know how or why

I am in the same boat. I have followed this video 3 times, and it's still not unlocking - https://youtu.be/_UdMUk4cN-o. I used both my guns in Armed and Dangerous, so I am really stumped here.

Not sure if this is the solution, but I would recommend making sure you play the mission to completion after getting the kills. I did it this way and never had any problems.

Thanks. I played up to a save point, but still didn't work.

Well, just did the same walkthrough again and the achievement popped. So relieved.

i missed armed and dangerous during campaign walkthrough, will achievement still advance if i kill robbers in this mission when starting this mission from "cases" menu, or do i have to restart playthrough?

You can replay the cases, and it'll count towards the achievement thankfully.
