Karte, Figuren und Zielmarke zeichnet jetzt Art. Die Karte zeichnet in Blöcken von 16 mal 16 Kacheln und nach einem Treffer nur die Blöcke um die Kachel neu; jede Kachel kennt ihre Nachbarn. Figuren stehen aufrecht in ihrer Kachel, schreiten und schauen in die Richtung, in die sie gehen. Der eigene Schlag zeigt seine Splitter sofort, auch als Gast, und die Namen über fremden Figuren werden in Bildschirmgröße gezeichnet und bleiben scharf.
