The bears are charging. The bulls are ready. Welcome to the Trial of Conviction. The Black Bull is a fast, colorful tower defense game where you command a herd of battle-hardened bulls against endless waves of bears determined to raid your basket. Place your towers, plan your upgrades, and hold the line through 60 escalating waves — if your conviction is strong enough. BUILD YOUR HERD Six unique bull towers, each with its own personality and combat style: • MinWage Bull — cheap, scrappy, gets the job done • BagWork Bull — heavy hitter that can evolve into the devastating Deadfall • Frost Bull — freezes bears in their tracks • Longhorn Sniper — picks off targets across the whole map • Whale Bull — massive splash damage, upgradable to the F.U.D. BUSTER • Bull Wif Hat — the legendary late-game powerhouse with three ultimate forms: STORMWIF, CHUMBA MODE, and VOIDWIF KNOW YOUR ENEMY Ten bear types with different speeds, armor, and tricks — from basic brown bears to iron bears, vampire bears, mama bears with cubs, and hulking kodiaks. And when the sirens sound, the F.U.D. blimps arrive: armored monsters that will test everything you've built, capped by a wave-60 finale.
