Well I was going for the Elemental Kill achievements and the achievement where you run over 25 enemies. I checked and it turns out I have a LOT of kills for each, more than required for the achievements. Any idea on why I didn't receive them?

glithced chevos.. my friend/many people have same problem's

try them while playing solo..

Cool! Gonna make a Siren when I turn on my Xbox and watch a bunch of achievements pop up

i had done all the aird badlandsquests done and i didnt get the achievement untill i killed destroyer

Wtf. I made a new character, the Siren, and I didn't get any of my glitched achievements. But I did manage to get My Brother Is An Italian Plumber and That's Outrageous...

I need to know how the fuck to get my missing GS ._.

Trying playing it by yourself without people in your game. From what I've heard, if you're trying to get certain achievements and other people are in your game and are doing them as well, it can glitch them.

Fucking shit...I guess I'm just gonna get my missing achievements on the Siren and run through the game on my Hunter.

lol, i played against your younger bro earlier in tf2 was doing hella bad lol, had a bad controller
