Mech Monkeys rejoice, this is a game you can enjoy.
You have the option of buying and custimizing mechs. You can configure them to whatever you want, and once you start to get the hang of the game, you won't ever go out in the stock configuration. You can also custimize your wingmates mechs, including paint jobs, to make it easy to tell which mechs are yours.
Gameplay rocks, even if it is a somewhat of a slow burning. Several missions will require patience and some can be quite frusterating, though you always feel as though you are in control of a five story monstrosity, not a guy walking around with a rifle. It does an excellent job of defining itself there.
The story is weak, and will probably be nigh indecipherable for those people who haven't read the books. However, for those who have at least a little bit of background knowledge in the BattleTech universe, here is a chance to play some of the famous battles from the Steiner-Davion civil war. Quite impressive.
Overall, it is fun if you are into BattleTech, and can be even if you aren't, but this is not a straight forward shooter, this takes more practice and skill than keen eyesight and reflexes.
