バトルフィールド — About this game

This overhead action shooter has weapons and upgrades to collect and a boss at the end of each era. This version uses an eight-way joystick and two action buttons. It has no separate rotary aiming controls, so use this version’s controls rather than trying to turn the gun independently of movement.
