Darius Twin
Darius Twin is a shoot 'em up video game that appeared in 1991 for the Super NES. It was the first new installment in the Darius series not developed for arcades, and also the first to have a normal 4:3 screen ratio. Interestingly, although it is a unique game in the Darius series, it seems to reuse sprites and background designs from Darius and Darius II. Even though the names of the bosses are new, they are mostly revisions of previous bosses.
