I didn't know anything about this French company - worth reading.

I thought I had never heard of them, but then I saw the screenshot from the ST title Action Service, and I'm pretty sure I've played that. Had no idea about their other titles, though their late-80s releases seem nice...
Two of their early Amstrad titles Night Boosters written by Gilles Bertin (a Tron Clone) and Cobra written by H. Heijnen (a clone of Snake) in 1985, made use of Hisoft Pascal 4t! :D
Muder on the Atlantic is probably the most gorgeus physical release that i´ve ever seen for the Amstrad CPC.
