How to Play Fatman
Quick start
First, we check the normal attack between Rex and remember the special attack and magical trigger time before we get close to the opponent. The prize money of each game can be used for strengthening physical and attack power and magical purchase, so consider not only fancy tricks but also money left in the next fight.
Controls
The A button is usually attacked and pressed to make continuous attack. B button is a bonus/special attack with long press and C button is used to purchase and equipped magic. The character’s uniqueness is triggered by combination of direction input and each button. START is used for game start and menu decision.
