Bloons TD 4 Expansion Unblocked — Play Free Online

Bloons TD 4 Expansion builds upon the refined mechanics of the fourth installment in Ninja Kiwi's celebrated tower defense series. Designed specifically for players who have mastered standard layouts, this standalone expansion delivers fresh, intricate maps that test your positioning and economic planning from the very first round.

Each stage presents distinctive routing challenges, featuring winding lanes, split paths, water hazards, and tunnels that obscure advancing bloons. Whether placing high-rate Tack Shooters at tight corners or positioning Long Range Darts along straightaways, every map demands a tailored placement strategy to handle increasingly dense waves of ceramic, lead, and camo bloons before the dread MOAB blimps arrive.

Because the expansion retains the progression system of the core game, completing rounds steadily awards experience points that unlock advanced towers, specialty upgrades, and track ranks. The loop of managing farm revenue alongside frontline defensive power makes every attempt a rewarding tactical exercise.

How to play

Pick a track from the level select screen to begin your defensive assignment. Use the mouse to select towers from the right-hand panel and click any valid terrain on the map to place them within the circular range indicator.

• Placing Towers: Click a tower in the sidebar menu and place it along the track with your mouse.
• Upgrades and Targeting: Click an existing tower to inspect its range, switch its targeting priority between First, Last, Strong, and Close, or purchase upgrade paths.
• Starting Rounds: Click the Start Round button or press the Spacebar to launch the incoming wave. Toggle the fast-forward icon to speed up popping action.
• Economy: Earn cash for popping bloons and completing rounds, or invest in Banana Farms early to fund high-tier Super Monkeys and Spike Factories.

Tips for mastering expansion tracks

• Prioritize Camo Detection: Invest in towers with innate camo reveals or radar support before wave thirty so stealth waves do not slip past unnoticed.
• Funnel Around Chokepoints: Place Mortar Towers and Boomerang Monkeys at overlapping bends where bloons must travel in tight clusters.
• Scale Income Early: Placing a Banana Farm during quiet early waves yields steady bonus cash, making late-game blimp rounds far easier to manage.
• Anchor the Exit: Always position a Spike Factory or high-speed Dart Monkey near the track exit as an emergency safety net.
