Hellfire (2P set) — About this game

Hellfire (2P set) makes shot direction the central choice in a side-scrolling spacecraft run. Four weapon patterns cover forward, backward, vertical or diagonal lines, and each retains its direction while the ship moves. A turret behind the craft may therefore call for a rear shot, while a protected installation can demand a diagonal approach. Power pickups strengthen the weapons and speed items change handling across the six-stage route. Learn the change-button cycle before entering a tight passage, then select the needed firing line early enough to keep attention on avoiding scenery and bullets.
