Shoulda posted this sooner, but after playing it on Normal I went back and played the 2nd part of the Omega Supreme battle on Hard, and it also said that I'd played the whole level on Hard.
It works for every other level, just play the last part of each level on hard and it's the easiest way to get the Autobot and Decepticon Hard Campaign achivements.

 

it's under the trophy and achievement sticky threads, but thanks

 

What's the fun in that? I was thinking that could of been a possibility of doing that, but I didn't try it. I re-played the whole game on hard. I find it more enjoyable that way instead of just going to the last level on each chapter on hard and beating it, but to each their own.

 

the only part i skipped was the defend ratchet/ omega supreme. that is just horrible on hard, i had an easier time taking down Omega in the decepticon campaign.

 

I agree with this. I like having the satisfaction that I beat the entire campaign on hard, even if it took me quite awhile. I had fun though.

That was the only part I had trouble with too, I had to have my boyfriend help me on Co-Op with that. There was no way I would be able to beat that part on my own.

 

Alot of people have known this.

 

That one took me a few times to do. Got a little irritating, but once I beat it, oh man. That was a great feeling.  

 

thanks for the tip
