I am owning this game on CD for the german market. With german text and speech.
It has a fantastic gameplay, has an optic like a arcade-automat and a phantastic soundtrack by "Chris Huelsbeck" (Tunnel B1, Giana Sisters, Turrican, ...).
The Engine is the same as "Schleichfahrt" / "Archimedean Dynasty", i read somewhere.
Also it exist a "Voodoo"- and "Direct X"-Patch for better textur-mapping and -filtering, i read a long time ago, but i never found it.
This game runs on Win XP and Win7 without any problems. I think, there is no DRM installed on this CD.
This game must be reactivated for all gamers these days!
On Youtube you are finding many Videos about this game.
