The guys from Natsume who released a great remake of Wild Guns are year ago are now remaking The Ninja Warriors Again from the SNES, which was one of the most underappreciated beat 'em ups of all time. Single-plane beat 'em ups are still a rarity. Remake will feature remade backgrounds, character art and animation, a new soundtrack, co-op mode, bigger field of view, and even two new playable characters teased on their site. One which appears to be the silhouette of a loli ninja robot who is supposed to be the technical character, and some huge guy twice the size of Ninja who is supposed to be the Heavy character here.
Coming next year for the Switch only, because of publishing rights or whatever. Play the original TNWA for the SFC if you haven't already, and make sure it's the Japanese version. The Western version cut out an enemy type completely even though it added a lot to the game.
