Dogyuun
First released in 1992 by legendary Japanese shoot 'em up developer Toaplan, Dogyuun stands as one of the most beloved underrated arcade STG titles of the 1990s. Set in a distant sci-fi future, the game follows a squad of human fighter pilots tasked with repelling the invasive Dogyuun alien mechanical empire, which has seized control of multiple colonized planets across the galaxy.
