This one is a bit tricky because there doesn't seem to be a way to check your progress. It will only show up on the right-hand side of your screen for 25/150, 50/150, 75/150, etc. The progress bar for each weapon in the challenges menu are for all enemies killed with the respective weapon (this includes human and murderbots, which doesn't contribute to the achievement).
For my situation, I knew for sure I had killed 25 aliens with the dubstep, abduction, and bounce rifle. I began using the black hole gun since that was my least used weapon, and luckily, "Experimental Tech: 125/150" popped up on my screen. What's left was the disintegrator and inflato-ray, so I just alternated between them until the achievement popped.

I can confirm this achievement is buggy on the 360 version of this game. I had a lot more than 25 kills with each gun but no achievement. I then got a final kill with each gun and it popped. Very strange achievement.

you can track the following through the challenge list Bounce Rifle, Dubstep Gun, Inflato Ray and Disintegrated. There is also challenge for the Abducted and Black Hole but not sure if you can track kills with it.

The challenge list is inaccurate, it registers kills for some weapons and aliens for others, i literally have everything above 25 kills and i still don't have the cheevo

i agree the challenge list is messed up, the last thing I needed was the black hole gun and when I unlocked the gun the total showing in the challenge list was 15 from doing the mayhem activity that gives you the gun, I went to the restricted zone to get some kills and after looking at the challenge it showed that I had 33 kills but the achievement didn't unlock. it finally unlocked after I was screwing around and getting my noteriety up I got the final few kills that I needed.

How do you unlock all the weapons?

You can unlock more weapons by finishing missions.

Glad I read this. All of the weapons showed way more than 25 kills in the challenges menu, but after checking this I went back to using the Inflato Ray since I hardly used that one.
On the first alien I killed the achievement popped.

I agree with the challenge list being inaccurate, for this achievement I had more than 25 kills for each of these weapons. After messing around, and finishing the DLC the achievement finally popped.

Do the police officers count as aliens?

Got way over 25 for each weapon and it won't pop. Achievement is buggy in a bad way.

I agree, this achievement is buggy! I have tallied each of the kills with all guns listed and it isn't popping! So frustrating.
EDIT: Just had to wait a bit and it ended up popping!

Needs the bug flag cause it's very buggy

Idk if its just me but it seems the inflato ray only counts secondhand kills. So the enemy inflating and popping doesn't count, but those around that die from the pop do. My counter went from 5 to 25 pretty quick in the first fight of the Nyte Blayde mission.

I can't seem to find the black hole gun or inflato-ray anywhere in the stores or weapon cache? I'm in post-game with both DLCs completed and 99% overall completion.
