Not a bad way to kill a couple of hours.`
First the bad: Too Few missions. More missions would have made the game have a more lasting impression. Much more playable in the long run. Second, The mission structure seems to be put together a little slap-dash.
Third, the model boxes that are unlocked. I must have missed the point of it.
Now the good. The fast pace and good controls give you a pretty good rush. It's pretty fun to try out different combos of mechs and weapons. But no new environments are unlocked so you use them on the same old targets as before.
