BIOHAZARD 3 is the name of a cancelled game in the Resident Evil series. It is unrelated to Resident Evil 3: Nemesis.
According to some sources, the plot of BIOHAZARD 3 involved the character HUNK, a USS agent previously seen in Resident Evil 2. In the story he was to be caught up in a viral outbreak on a cruise ship. A common enemy time was intended to be plant-based.
The game was the brainchild of Hideki Kamiya, who had previously directed Resident Evil 2. He imagined a cruise ship as a logical step for the franchise in keeping to original settings. With the approach of the PlayStation 2 games console, Kamiya was instructed to abandon development for the old console, and development stopped in mid-1998. Moving the team over to another BIOHAZARD 3, the entire plot was rejected and Kamiya chose to start all over again. Some aspects of the game may have been recycled for 2002's Resident Evil: Dead Aim, which also featured a viral outbreak on a cruise ship.
