Jet Force Gemini

Jet Force Gemini for Nintendo 64 is a 1999 science-fiction action adventure from Rare, released in North America on October 11. Set across a threatened corner of the galaxy, it follows the law-enforcement team of twins Juno and Vela and their cybernetic dog Lupus as they oppose the insectoid warlord Mizar and his Drone army. The mission begins after Mizar's attack scatters the team, then turns into a wide-ranging hunt through alien worlds for survivors, ship parts, and a route to the enemy's stronghold.

At its center, Jet Force Gemini is a third-person shooter built around exploration. Players run, jump, swim, climb, and battle through large 3D areas, collecting ammunition, health-restoring gems, keys, upgrades, and an expanding stock of weapons. A dedicated aiming view places a crosshair on screen for more precise fire, while normal movement retains the perspective of a 3D platform adventure. The result asks players to switch between navigating elaborate environments and dealing with dense groups of hostile creatures and machines.

The campaign is divided among three playable heroes whose specialties shape the route through the game. Juno can cross hazardous magma, Vela can remain underwater without an air limit, and Lupus can hover briefly to reach distant platforms. Their early paths are separate, but once they reunite, previously visited worlds can be revisited with the character best suited to a particular obstacle. That structure makes equipment, movement abilities, and thorough exploration important rather than treating each stage as a one-way shooting gallery.

Mizar has enslaved the small Tribal people, so rescuing them is a major part of progress. Tribals are found throughout the campaign and can be harmed in the crossfire, which makes careful target selection matter during chaotic fights. The team also searches for components needed to restore an ancient starship. Saving the Tribals and assembling that craft eventually opens the way to the final confrontation, giving the game a collection-and-rescue objective that runs alongside its combat.

Rare filled the N64 game with tools for different situations, including basic firearms, heavier explosive options, grenades, a sniper rifle, and a flamethrower. Weapon pickups and capacity upgrades broaden the arsenal as the journey continues. Juno, Vela, and Lupus are later aided by Floyd, a floating robot, and a second player can control Floyd's targeting support in the single-player adventure. The Nintendo 64 release also supports the Rumble Pak, fitting its fast, impact-heavy battles.

Beyond the main quest, Jet Force Gemini includes competitive multiplayer for two to four players. Its deathmatch options allow changes to items, victory conditions, and time limits, with additional characters and arenas unlocked through campaign progress. It also contains top-down racing challenges and a firing-range-style target event, giving the cartridge several modes outside the story. In Japan, the Nintendo 64 release was titled Star Twins, a regional name chosen in place of the English title.

Jet Force Gemini arrived during a prolific period for Rare on the Nintendo 64 and combines ideas associated with arcade shooters, platforming, and free-roaming action games of the era. Its colorful planetary settings, character-specific traversal, rescue requirements, and extensive extras distinguish it from a straightforward corridor shooter. The original game later returned in Rare Replay on Xbox One, but the Nintendo 64 version remains the foundation: an ambitious interplanetary campaign centered on Juno, Vela, Lupus, and their fight to stop Mizar.
