Action packed time waster.
It by far isn't up to this current gen's standards, but it has it's own bargain brand of fun in the form of blasting giant bugs, UFO's and robots. There is not much of this game to explain, except that you shouldn't expect a blockbuster of a game, but rather one of those titles that you would borrow for some cheap fun, then give it back. Oh yeah, there is a lack of proper vehicles, as there are four types to choose from. You have a "Star Wars" type of speeder bike which only has guns, a tank, a mech suit that is very clunky to turn in, and a helicopter. All vehicles cannot take any real type of damage, being that it doesn't take much to destroy them.
One of the best things to do in this game though, is to launch an Air Tortoise at a giant robot.
