Prodeus

Same thing happened, 100 popped but not the 20.

That I'm not sure about. The achievements popped correctly for me but I have had some weird achievement issues with this game so its possible the 20 is buggy

Actually just speculating - the achievement for 20 is for friendly fire and not just kill each other. I did notice that the Prodeus enemies killing normal ones in the campaign did not seem to unlock the 20, because I let them kill quite a few and it did not unlock. As they are naturally aggro to each other, maybe that doesn't count? If anyone fan confirm, I'll edit this solution and delete my 20 kill solution

For those who did not pop 20 - Can you search on my name and try the Actual Friendly Fire map I just uploaded? It uses the same enemy class that are not aggro on each other. Let me know if that works and I will update all solutions.

New map worked great. Thumbs up.

Excellent! I will go update the solution over there - give it an upvote. Thanks for the help.

Thank you got it.

Finally popped for me. I went way over 100 kills with "Actual Friendly Fire" map without achievement. Then I used "in-fight" map once and it popped after couple of kills. Same thing with 20 friendly fire kills achievement, but the other way around with the maps.

Yeah I'm not sure if the friendly fire kills count towards this. Pretty unclear. And some of the achievements seem a little buggy so it's hard to tell. Glad you got it!

tried it. for me, 20 popped but not 100.

20 popped, 100 didnt

I'm not sure why the 20 is popping but the achievements in this game are a little weird. Are you playing on Xbox or pc?

Achievement's are popping on your created maps with no issues on Xbox series X but not through windows 10. Maybe others could say what they are playing on.

Update. It wouldn't unlock using this new map on the xbox either.

Weird. I played on windows and all unlocked normally. I'm not sure.

It's probably just a issue with the game itself.

Yeah, there's an issue with the game. Nothing was popping here, I closed the game, opened it up again, went to my dowloaded maps and entered this one again, this time on medium. Both achievements popped at the same time.

All my achievements unlocked but some definitely didn't unlock when I expected them too, so I agree. Probably just slightly buggy for a lot of these. Love getting downvotes for that lol

had to play it about 5 times but got the 100 achievement using the custom map

People having issues, I had 40+ before the 20 registered. Its either buggy, or what we think counts, doesn't. Like if two enemies attack one, then maybe that one doesn't count. I don't know. But 1 does not seem to equal for a few achievements in this game. I would say get like 2x what you think you need.

Can confirm it works, not sure if playing on medium difficulty really has an effect on the achievement, but i did do this on medium difficulty to be sure

Yes, I unlocked it while testing these maps in the editor lol

Seemed to work just fine for me personally. Played the map 3 times and unlocked this.

Xbox series X, played this through 10 plus times and not unlocked .All the other maps worked fine

Not sure, the Series X/S seem to be really buggy in general if you're using quick resume, and the tracking in this game is definitely weird. I would restart everything and try again, but past that I don't know.

I tried all of that I think I've played the map about 30-40 times now but hopefully it will pop randomly all the other achievements have been fine so far

Just emphasizing this for anyone misreading this:
This achievement is for blue-on-orange / orange-on-blue kills.

So not blue-on-blue / orange-on-orange like the Friendly-fire achievement.

^{Shadow Echelon does mentions this.
DM me if anyone wants my 2nd discount coupon for SpecSavers.}

Thank you based crazy dutchman

Thanks for that

Done 10+ runs of this on medium and still nothing (Windows). Weird.

EDIT - This finally unlocked for me on the 13th try. This map does something weird to the game on PC. I gave up and went to get the pacifist achievement instead but that wouldn't unlock either. I closed the game and tried to open it again but it would not open, at all, until I rebooted my PC. I got the pacifist achievement then did 2 more runs of this and it unlocked. Probably useless information, but it does work ... eventually.

Its also worth noting that after getting this achievement, out of curiosity I closed the game again to see if i could reopen it, the answer to that was No and I needed to reboot again.

I honestly think it just doesn't track properly. Re-opening might make it work. I definitely got the 20 friendly fire way after 20. Not sure.

My game also never opened on the first try, had to restart after a wsreset.exe every time to get it to open. I've had that issue with other games from windows on PC like Halo as well. Not map related.

For some reason I cant connect to Pronet through the Xbox network, but I found out you can get this yourself in the map editor.

I have no idea what I'm doing, but I went into the assets menu and made myself a wall of doors, and stuffed the opposite side with Prodean and Chaos enemies, then went to the play menu, and just restarted the level whenever the chaos enemies were killed off. I think I got it in three restarts.
