So I play exclusively with my gf, not online. Weve beaten terra on both playthroughs but havent gotten the achievement. Anyone else have this happen?

Not to me but it happened to my friend and all we did to get it for him was kill it a few more times and he got it on the fourth kill. Try kill it again and the achievement that u want might pop up

Thanks, that at least gives me hope.

You also have to turn in the mission afterwards for the achievement to pop. I too was concerned after I first killed him and did not immediately hear that pleasing cheevo sound.
