Released in July 1986.
Bronx is a bootleg/hack of "Cycle Shooting
". The game is much harder and Lives settings are different than in Cycle Shooting:
You start with less lives with default settings (2 instead of 3).
You can't get any extra life.
You start the game as if you had already sustained 8 'steps' of damage.
Furthermore, the game starts as if you had completed the 6 stages 8 times.
