Let's Play Ninja Baseball Batman (Arcade 1993)

If you were ever wondering if anyone ever made a game combining ninjas, baseball, and batman, well - wonder no more. In this 1993 classic arcade game mega-hit (that I never heard of) we discover the ultimate in ninja/baseball side-scroller beat 'em ups: Ninja Baseball Batman.

From the Wiki: Ninja Baseball Bat Man, known in Japan as Yakyū Kakutō League Man (野球格闘リーグマン Yakyū Kakutō Rīgu Man?, "Baseball Hand-to-Hand Fighting League Man"), is a 1993 beat 'em up developed and published by Irem Corporation in association with its North American division Irem America exclusively as an arcade game. It is the fourth arcade game by IREM to use a belt scroll perspective, following Blade Master, Hook and Undercover Cops.

The game allows up to four players to play simultaneously. Each player chooses from among four characters. The object of the game is to recover various artifacts stolen from the Baseball Hall of Fame, a task prescribed to them by the Commissioner of Baseball. https://en.wikipedia.org/wiki/Ninja_Baseball_Bat_Man
