Originally released by Game Arts in 1986, this title is a side-scrolling action shooter. Players pilot "THEXDER," a Hyper Dual Armor robot capable of transforming into a jet, on a mission to destroy the magnetic field generator on asteroid Nedeam. Across its 10 side-view stages, success relies on switching between two forms: the robot, which fires homing lasers but lacks mobility, and the jet, which moves swiftly but can only attack straight ahead. Players can also deploy a defensive shield, but managing its energy use is critical to avoid running out of power.

A retro robot staple, this classic balances high difficulty with addictive replayability. Featuring a compelling world, outstanding mecha design, and smooth transformation animations, every detail is meticulously crafted.
