Step into the arena. Duellum is a fast-paced deck-building card game set in ancient Rome, where every decision shapes your path to victory. BUILD YOUR LEGION Start each battle with a basic hand of soldiers and coins. Spend gold to recruit powerful new cards from the market -- fierce warriors, cunning tacticians, and devastating war machines. Every card you add transforms your deck into a unique fighting force. Will you build a lean, efficient strike team or a sprawling army that overwhelms your rival? FIGHT FOR GLORY Deploy your cards to deal damage, generate gold, draw reinforcements, and unleash devastating combos. Banish weak cards to sharpen your deck. Time your attacks carefully -- a well-built engine can end a battle in just a few turns, but one wrong move and the tide turns against you. PLAY YOUR WAY Challenge the AI across three difficulty levels -- Easy, Medium, and Hard -- each with its own tactical personality. Or take the fight online and battle a friend head-to-head via Game Center with turn-based multiplayer. Take your turn whenever it suits you -- during a coffee break, on the bus, or late at night. Your rival will be notified when it's their move. EARN YOUR RANK Rise through the Roman military ranks as you rack up victories. Start as a humble soldier, earn the title of Decanus at 10 wins, command as a Centurion at 50, lead as a Legatus at 100, rule as Imperator at 500, and achieve the ultimate honour -- Caesar -- at 1,000 victories. How far can you climb? COMPETE ON THE LEADERBOARDS Track your Total Wins against players worldwide. Race up the Weekly Wins leaderboard in fierce seven-day competitions. Or prove your tactical mastery on the Fastest Victory board -- can you end a battle in record time? UNLOCK ACHIEVEMENTS Over 20 achievements reward skilful play and daring strategies.
