Fantastic game for an older one.
Is quite fun when being able to drive in a tank or a helicopter or an alien ship or just a gun turret on the ground. Compared to games nowadays though it of course lacks storyline and is just you fighting against aliens to protect the planet so it doesn't really need one. Game play is quite good and graphics arnt too bad for a game of its time.
I lost this game in the cupboard for about 6 years and because of this I had my high expectations when I went back to it and when I finally found it (about a month ago) I installed it and played it and found it wasn't as good as I thought it was. If you want something with good game play and just fast paced action then give it a shot.
