You're staring down wave47, your Monkey Village is buffing three lanes at once, and a cluster of camo leads is about to blow through your last checkpoint — this is Bloons Tower Defense 4 Expansion, the bigger, harder, more obsessive version of the classic balloon-popping strategy game. You place and upgrade towers along a path, and your job is to stop endless waves of Bloons from reaching the exit before you run out of lives. Every round you earn cash, and every dollar matters — do you rush the Monkey Bucaneer or double down on your Dart Monkey farm? The strategic depth here is real, and one wrong call on round30 can cost you everything by round 60. Think you can hold the line all the way to the end?
How to Play & Controls
- Left Click — place a tower on the map or select an existing one
- Left Click on tower + upgrade buttons — buy upgrades using your in-game cash
- 1-9 keys — quickly select towers from your build menu
- Right Click / Escape — deselect a tower or cancel placement
Tips & Tricks
- Start with a Tack Shooter or two near tight bends — the grouped hits carry your early waves further than single-target towers.
- Rush the second-tier upgrade on your best DPS tower before branching out, because half-upgraded towers spread thin and let leads slip through.
- Camo and regrow Bloons show up mid-game without warning, so drop at least one Mortar or Ninja Monkey before wave 35 or you'll regret it fast.
