Transformers: War for Cybertron

This achievement is to kill brutes (the big bots that have a big sheild on their left hand)

All you do is let the computers/friends distract it and you have to get behind it and shoot the little pack on their back.

Repeat 5 times.

Note that you have to be the one doing the finishing shot on the back in order for it to count to the achievement.

If for some reason you find yourself missing a few of these after playing the campaign, load up checkpoint Chapter VI: Defend Iacon: The Broken Lift. Play as Optiumus Prime.

The first enemy you face is a brute. Use Prime's boost ability (LB) to get behind the brute and shoot the box on his back. It takes several hits to destroy them.

You only get credit for brutes that you deal the final blow to. Once you've beat him, restart the checkpoint and repeat until you've got your five.

same as above but i got in the eceration mode aka transformers horde mode brutes are the guys with the blue shields and they come around wave 7
