Jet Force Gemini
宝石力量
Jet Force Gemini is a 1999 action game developed by Rareware for Nintendo 64. This third-person shooter combines combat and platforming across alien-infested planets. Players control Juno and Vela along with two combat robots, exploring environments from an over-the-shoulder perspective. The jetpack mechanic enables hovering and aerial navigation necessary for traversing levels. Combat uses lock-on targeting for defeating alien enemies with various weapons. The game supports cooperative multiplayer for up to four players completing campaign missions together. Players collect ammunition, health items, and power-ups while solving environmental puzzles. Each planet functions as a distinct stage with multiple objectives requiring combat ability and exploration to advance. The N64 controller's dual-analog setup enables simultaneous character movement and camera control during gameplay.
