Hey, need help with a movie title. I saw a trailer a while back. Now I can't find anything about it.

Anyway, here is the basics of the trailer.

An "peaceful" alien race contacts earth to warn of an imminent attack from hostile aliens. They send plans for an exoskeleton type thing to fight the aliens. Turns our the "peaceful" aliens where the ones that were going to attack and where able to hack the suits and use them to take the earth. A lone suit was found and will be used to fight back.

That is the basics of it, Russians and Americans where interspersed in there too. Anyway, hope someone can help with this. Thanks in advance for any help.
