Halo 4 Bigfoot Achievement Not Unlocking!

I was looking forward to getting this achievement today after I saw that on Waypoint, under map stats, that my mantis had 14 stomps on the map shatter. To my horror, I counted down the stomps and, when it reached twenty, it didn’t unlock. So, I went back to waypoint thinking, maybe I counted wrongly, and my mantis had 22 STOMPS!!!

Can anyone tell me what I can do, is there something specific to do to fix it or…

DO NOT say oh, it has to be in Crimson matchmaking, because I HAVE done it all on shatter, the stats from the mantis ARE from Shatter alone.

Any help will be greatly appreciated, thanks.

I’m having the same problem. I have 24 stomp kills by now… :frowning:

Did you do it online or in customs?

Same problem i’ve got 21 and i havent got it how do u fix???

I’ve heard stomps against vehicles count towards your stats but not the achievement - just keep going and you should get it.

Yeah ive got a few against ghosts so ill keep trying thanks very much :slight_smile:

Alright, shouldn’t be too long for me then because I haven’t stomped on many vehicles, maybe 4 or 5 so… 2 or 3 more stomps to go…
Thankyou all!

If you stomp a ghost you get 2 kills but only one of them counts towards the achievement.

Stomping a vehicle will show 2 kills for your stats but is only 1 kill towards the achievement.

Just keep doing it and you’ll get it sooner or later.

Bummer man…be glad it isnt the man cannon or warthog achievements. Those were a pain in the butt (if they didnt glitch for you :-). ). I really enjoyed stomping kiddos with the mantis

I got mine around 22 possibly 23.

I went back through my Waypoint stats and checked how many on DLC maps I got was a few over from what it should have been.

So keep trying.

The achievement description tell you that you need 20 mantis stomp kill in the DLC playlist to unlock.

Does this have to be in playlist or can it be in big team on shatter?

I had the same issue, it could be you have to get that map only in the crimson playlist, not playing btb and that map come up. I had like 22 before it unlocked and it also said all were on shatter.

Yea it definitely has to be all on shatter I just dont know if it has to be the crimson DLC playlist…
