SMASH EVERY CASTLE. RULE EVERY ARENA. Build your defenses, choose your crew, and smash your opponent's hard work to pieces in Castle Busters, a turn-based online PvP battle game. Just you, your rival, and two castles that won't both survive the match intact. And you'd only just finished decorating! MAKE EVERY SHOT COUNT Take aim and fire. Your crew brought the firepower. Your opponent kindly supplied the target. In fast 1v1 battles, every shot changes what happens next. Blast through walls to open new angles and collapse towers to expose enemy heroes. Win by taking out their entire crew or turning their castle into rubble. With physics-based artillery and a battlefield that falls apart, you'll need to think on your feet. They can't hide behind a wall you've already demolished. DRAFT YOUR CREW Some heroes bring the damage. Others rally the crew to hit even harder. And some bring teammates back from the dead because nobody said they could leave yet. Mix and match heroes whose abilities work together. Build around your favorites, discover powerful combinations, and find a crew that suits your playstyle. YOUR CASTLE. YOUR DESIGN. Build a castle worth showing off, then roll it into battle. Yes, it's on wheels. Fortify your walls, position your heroes, and choose gadgets that suit your strategy. Test your setup in battle. Putting your plan together is almost as satisfying as watching theirs fall apart. RAISE YOUR GAME Level up your heroes and unlock new faces for your crew. Each new arrival brings a different ability to play with and another reason to rethink your lineup. Earn rewards from the Forge as you upgrade your squad and stronghold. Who knew you could get rewarded for being such a destructive influence? CLIMB THE RANKS Earn trophies and progress through the arenas on Trophy Road. Unlock Ranked mode and compete on the leaderboards for rewards and bragging rights. You'll need to outthink your rivals, not just outshoot them. The view from the top is lovely. Expect incoming fire. The arena is open. Go break something. FREE TO PLAY Castle Busters is free to download and play. Some in-game items are available for purchase. A network connection is required. Suitable for players 13+.
