ANNIVERSARY dlc achievements?

So yeah, I bought the map pack. I have a question about the achievements.
I remember there was a… dirty method how to complete the achievements in Defiant by downloading the game mode from your recent games and completing it in custom games.

Can I do the same in this DLC?

By the way, don’t come in here to flame and bash me.
You can’t decide how I’m going to play this game.

sorry man you could with the old defiant but you cant with the new btw there defiant DLC only so they cant be done on other maps just defiant making them very difficult

That sucks. The achievements are hard enough and now we even have to complete them on the maps nobody ever chooses? WTF?

yeah man there are a bunch of forums about it alot of people feel the same way including me
