if you can connect to Xbox Live, then it is mandatory that you download this game.
Graphics: As you first boot up the game, you will see fantastic graphics for an a Live Arcade game. there is actual cut scenes. Trees can get crushed by tanks and set on fire. On the first level you will be trying to fight both a large spider boss and dozens of little spider robots all at once. it can get pretty frantic
Gameplay: Shoot and shoot some more. if you lose you ship, you start walking on foot. This sucks a lot seeing that you can't move as fast and you're at greater risk of being killed, but if you can wait 20 seconds you'll get your vehicle back. the only thing i don't find balanced is that you can just can just kick back and heal after you've cleared a small area, which can kind of suck the fun out of it if you don't like that.
Sound: The music is alright, but you will hear a lot of recycled sounds and it annoys me .... so yeah....
Value: at ten bucks, the game is short and will seem expensive, but if you're into the old school style of shooting the crap out of things, you will definately enjoy this game.
