A year after the first game, the demon lord Ashtar kidnaps Irene Lew and threatens to open the Gate of Darkness, pulling Ryu Hayabusa back for Tecmo's 1990 sequel. The cinematic cutscenes return with more ambition, and the game builds on the first one's speed rather than reinventing it.
The headline addition is the Phantom Double, an orange shadow clone that follows Ryu and copies his attacks, up to two at once. Because clones stay where Ryu was a moment earlier, players can position them to hit enemies from several angles, and they make bosses far easier when kept alive. Ryu can now climb up walls rather than only clinging and jumping, which smooths out the platforming. Stages also add environmental hazards, including strong winds that push Ryu around and a stormy level where lightning briefly reveals the background. A slightly gentler curve makes it more approachable than the original, though the late stages remain demanding.

Grab Phantom Double power-ups and keep them alive; they triple your damage against bosses.
In wind sections, time jumps with the gusts rather than fighting against them.
The fire wheel and windmill star remain strong ninpo choices for crowded screens.
