Triggerheart Exelica (トリガーハート エグゼリカ Torigā Hāto Eguzerika, spelled Trigger Heart Exelica in Japan) is a shoot 'em up by Warashi, makers of the Sega Saturn shooting game Shienryu. It was released in Japanese arcades in early 2006. The game runs on Sega's Naomi hardware. It is the last Sega published release for the Dreamcast.
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.
