Biz was a game that was written by Alex Aris back in 1989, and was based on a modified version of a game called Street Bomber done by Tony Rushbrook in October 1984 (Commodore Horizons).
The game was a Blitz clone that contained multi-coloured graphics, music created in Ubiks Music, a high score table and 5 levels in total.
It was originally sent to Commodore Disk User, but sadly was rejected due to a bug with the distance of the bomb from the space ship.
Sadly Alex no longer has the game and has been desperate to find it. He believes that it was sent across Europe and as far as Australia – so it is hoped that it could still turn up.
