A year later a posthumous release graced the Japanese Dreamcast console, though in very short supply. And now, another year later, the Xbox Live Arcade has become home to this highly addictive shooter. Developed by Warashi, the people behind traditional arcade shooters like Shienryu and Sengeki Striker, Triggerheart Exelica is a vertically scrolling 2D shooter in the same vein. And while traditional arcade shooters all share the same basic formula, Triggerheart Exelica introduces some cool new mechanics to help it stand out from the rest."
