Kalisto er på vej med et nyt online action/RPG baseret på Highland filmene. Selv om Kalisto ikke er særlig meget for at komme med detaljer om spillet, så lykkedes det alligevel The Adrenaline Vault at få følge informationer ud af Kalisto:
Highlander Online will be a 3D action game with some unique twists. The plot will be crucial to bringing the action to life. The emphasis will be on combat and role-playing. The famous Highlander creed in which immortals battle until there is one remaining will exist in the game. Sword fights will be central to the combat. The few technical tests held to date were "a blast". There will be a training ground for newcomers. Kalisto is in negotiations with several different groups regarding server plans. Worldwide reach is critical to Kalisto's plans. The game will use Kalisto's Platform K engine, used in Nightmare Creatures 2 and retooled for the PS2 and x-box. Distribution and subscription plans will depend on the partner Kalisto settles on.
