U.N. Defense Force: Earth Joker (US / Japan, set 2) — About this game
Earth Joker offers four pilots and ships with different weapons for the assault to reclaim Earth. Power-up items strengthen the main attack, while support choices include forward, side and homing missiles or a weapon that bursts at a set distance. Holding fire charges the selected weapon, and releasing it produces a stronger attack. Switching between normal fire and a prepared burst changes how a formation is approached.
