According to Commodore User September 1988 in their PC Show 88 preview, Activision had secured the rights for Corland Technology’s Cyber Tank game.
We did a bit of research, and found it. At present hte game is not yet full emulated it seems, but seems to be a Battlezone/Thunderblade clone… http://www.youtube.com/watch?v=mvZwBja4Sns
The Games Machine had reported that Mediagenic had the rights to the home conversion of the game, along with SNK’s Fighting Soccer. Both games were listed down for a 1989 release,but it was pointed out that Mediagenic had their hands full projects wise as it was.
Nothing else surfaced about the game, so we can only assume that it was vapourware.
Do you know any more?
