Im trying to find this game I played approximately 15+ years ago. The only thing I can remember was that there were some kind of futuristic Tanks/Towers that shot lasers. Im certain you played a blue "Tank" looking thing and I believe the enemy was green. I also believe the game was played in top down view.
Hopefully someone can help me find this game. It keeps popping into my mind for years now but I could never find it.
