LEAD YOUR ARMY. CONQUER THE MAP. Take control of your hero, lead your army across a 3D hex battlefield, and claim the map in fast 1v1 real-time strategy battles. Build Barracks, Gold Mines and Defense Towers, collect legendary heroes, and turn every hex to your color before the clock runs out. Harbor Rush is a hero strategy game that blends real-time strategy, tower defense and hero collecting into quick 1v1 battles. Command your hero, outsmart your opponent with the right deck, and defend your base with towers that hold the line. Every strategy battle is a race for territory, and every hex counts. YOUR HERO LEADS. YOUR ARMY FOLLOWS. Move your hero and your army marches with it. Push through a weak flank, pull back to defend your towers, or charge straight for the enemy base. Use hero skills at the right moment to break a defense or turn a losing battle. In this real-time strategy game, your army is only as strong as the hero leading it. FAST 1V1 STRATEGY BATTLES Every 1v1 battle lasts 3 to 5 minutes. Grow your economy, break through the enemy line, and destroy every enemy building, or hold the most hex territory when time runs out, to win. Quick enough for a coffee break, deep enough to keep you coming back for one more battle. BUILD, DEFEND, CONQUER Every coin is a strategy choice. Gold Mines grow your economy, Barracks send heroes into battle, and Defense Towers guard your territory with classic tower defense firepower. Spend too much on defense and you fall behind; rush too fast and your base is exposed. Find the balance, then snowball your advantage hex by hex across the map. COLLECT LEGENDARY HEROES Every Barracks you build calls a hero, from Common up to Legendary, who fights for you all battle. Land a Legendary hero and watch the fight turn. Every hero brings its own attack style, so the heroes you collect shape your strategy. Level up your favorite heroes and discover new ones as you play. FOUR FACTIONS. ENDLESS STRATEGIES. Sentinels: iron-willed defenders who hold the line. Outlaws: cunning raiders who strike where you least expect. Crown: noble warriors who fight with honor and steel. Academy: arcane scholars who bend magic to their will. Each faction counters another. Match factions for bonuses, read your opponent’s lineup, and build the hero counter that wins the battle. BUILD YOUR BATTLE DECK Choose eight cards before every battle. Level up your heroes, test new combinations, and find the strategy deck that fits your style, whether you love fast rushes, solid tower defense, or a late-game comeback. CLIMB THE RANKS Battle your way up through seven ranks and unlock new ways to play: expand your home territory at Silver and wield powerful artifacts at Gold. The higher you climb, the tougher the opponents and the bigger the rewards. GROW BETWEEN BATTLES Earn chests, level up your heroes, and expand your territory. Unlock artifacts, powerful abilities you cast mid-battle to turn the tide, and upgrade them to make every cast count. Command your hero, master real-time strategy, and conquer the hex map.
