Completely forgettable story, but great fun sci-fi mech combat. Missions are generally easy and take less than 30 minutes each.
Very good part mix-match possibilities, you can anything between a tank with a huge rail gun to a fast flyng quick shot.

Incredible customizability of mechs, not just paint and decals of individual parts but also upload or create your own!

I do take half a star off for having to repeat the game three times just to get the full story (which again is bland).
