Triggerheart Exelica is a vertically scrolling shoot 'em up developed by Warashi for the Sega NAOMI platform. The game was first released in Japanese arcades in May 2006 and was later ported to the Sega Dreamcast becoming the system's penultimate licensed title when it was released in Japan on February 22 2007—only two weeks prior to Karous. The game involves playing 1 of 2 anthropomorphic fighters to battle against 5 stages of enemy ships. Exelica specializes in wide area attacks while Crueltear uses concentrated front shots. Players can fire anchors to catch enemy ships then use the caught unit as a shield or throw it to inflict more damage.
