Transformers: War for Cybertron

Begin the "Guardian on the Bridge" checkpoint on Chapter 4, Death of Hope.

Use Soundwave with his ram ability. Use your LT to boost, and at the beginning (and other straight stretched) use your RB to activate the Ram. Be careful when you make the jump... if you are Ramming right there, you may overshoot the second part of the tunnel.

The achievement should pop right as you hit the reddish section at the end of the bridge. I got it on my second try (because I overshot the break in the tunnel). Good luck!

You need to load
Chapter IV - Death of Hope,Checkpoint 8 - Guardian on the Bridge and pick soundwave. you pretty much need to drive down the chasm boosting as much as possible and you should get this easy. you can also do this with breakdown but its a bit harder.
im adding a youtube video also so you can see how its done.(video is not mine, kudos to the person who filmed it)

Using Soundwave transform and use your Ram Ability to get a speed increase at long streatches of road. If you go fast enough you shouldn't have to to worry about the mines.
Edit: Guardian on the Bridge is the load you should use.
Edit2: You must be the one to do it. Co-op doesn't help here.
