Abyssal Infants (HB) — About this game
Abyssal Infants (HB) brings kakoeimon’s side-scrolling shooter to Neo Geo with more enemies and hostile bullets than the Mega Drive edition. Dashing can be used more frequently in this version and adds shots, while single-player play controls both infants together. Later stages explain the upgrades earned along the route. A section-selection menu provides a way to begin at a chosen point, and a second player can enter or leave the run. Learn the spacing of the paired infants before dashing into a narrow opening, then read the next stage’s upgrade text before continuing.
