Apparantly it was ported to the ST but never actually released. Maybe somebody from Electronic Arts would like to put the game engine into the public domain, so we can buy PC copies of the game and use the graphics and sound files from that?
That's how the Atari versions of Doom and Quake work - as long as you own the game you can run the engine on any computer you have, it's only the levels and graphics etc. that are protected. But you can't run it on more than one machine at once unless you have more than one copy of the game.
