My childhood memory's probably a bit muddy, but if anyone thinks they can recognize this game I'd be very grateful
I played it around pre 2002. I think..
It was a Sci-fi future theme, first-person-perspective game.
The Player's goal was to pilot a space train/truck to the next port while avoiding and fighting off various police ships.
Your ship was locked to a set of rails, there were walls to either side of you and you were always moving forward. You had to decide which direction to go when forks in the track came up.
You were attacked by various police vehicles that would fly onto your screen, which you could destroy by aiming and firing lazers with your mouse.
The most common enemy was a police robot drone shaped like a lollipop with a square head and flashing police lights on top.
The next enemy up from that was a police ship shaped like a semi-circle with two cockpits on the flat side.
The most dangerous enemy was a large dark-yellow ship called a 'Scorpion'.
You only ever saw profile pictures of characters in the game. I think your character had a trucker cap.
The game had a lot of CDs, and came in a multidisk jewel case.
Any help greatly appreciated, I've been looking for a long time.
