Forum:Mass Effect Achievment Help

Hey, does anyone know if you have to change your charecter to get the tech and biotic acheivments or can you use them through your sqaudmates. Also, how do you get the ally acheivments. I played with Wrex and Garrus almost throught the whole game and I did not get the Krogan and Turian medals. What Gives? Help would be great, thanks WRAITH 21:05, 7 January 2008 (UTC)
