This is a prototype of Floigan Bros by Visual Concepts. It contains watermarks of the build date (Jan 21, 2001) and the Visual Concepts logo. Instead of the game’s title in the header, it uses the default “THIS IS A SAMPLE DISK FOR USE INTHE OFFICE ONLY / DO NOT SELL / DO NOT CARRY OUT FROM THE OFFICE”. It also contains various bugs which do not appear in the retail version.
Massive thanks to CombyLaurent for sending this in for release!
