TowerAttacker is a fast, touch-first strategy game where every defense, Camp, and army changes the battle. Fortify your Core with Resource tiles and specialized towers. Upgrade Resources through ten levels at any HQ level to increase their Gold payout, durability, and crystal presence. Spend Gold once to build one of seven Camps, then continuously deploy specialized armies at no additional Gold cost. Every Camp type shares one global wave cycle, so your whole mixed army deploys together and new Camps join the next wave. Gremlin Camp alternates between Max and Jazzbo armies. Upgrade Camps to add more armies to each wave and gain more health without changing the wave timing, then protect them from enemy Sappers and Siege. Choose Battle CPU and pick Easy, Medium, Hard, or Jeremy Rage Mode, or use Apple Game Center to invite a friend or find another player for a two-player battle. Tap the Jeremy Thief spell to send him from your HQ to steal enemy Gold. Learn the controls in the live Tutorial and explore the optional War Room field guide. Features: - Fast real-time tower defense and army combat - Direct touch placement for Resources, defenses, and specialized Camps - Ten Resource levels with stronger income, durability, and crystal growth - Seven Camp types that continuously deploy free armies after construction - Jeremy Thief and four area spells with distinct battlefield effects - Four CPU difficulty levels, from Easy to Jeremy Rage Mode - Ten Camp levels with larger wave contributions and more health - Targetable Camps that must be defended from Sappers and Siege - Distinct tower roles with targeting, projectiles, damage stages, and upgrades - Ground, flying, swarm, siege, and specialist army units - HQ progression that expands your economy and defensive options - Offline CPU battles with no account required - Native two-player matchmaking and invitations through Apple Game Center - No ads, subscriptions, or in-app purchases Build your Camps.
