Play Online Bloons Tower Defense 4 Expansion
Bloons Tower Defense 4 Expansion builds on a simple idea and adds more ways to pop. It brings fresh tracks with tricky layouts, split paths, and tight corners. Some maps push water lanes or long loops that reward good coverage. The pace stays fast, and the bloons ramp up in a steady way. You watch the path, spot gaps in your setup, and shift plans as new bloon types show up.
The tower roster gives you lots of tools. The Dartling Gun follows your aim and shreds clumps when you track it well. Mortar drops precise blasts where you set the target and clears waves that bunch up. Monkey Ace circles the map and hits wide areas, while Spike Factory protects the back line and saves runs that go wrong. Glue and Ice slow the rush so Bombs and Tack clean up. Leads need the right damage, and camo needs detection from upgrades or support towers, so timing and placement matter.
The expansion adds modes that change the rhythm. Sandbox lets you test builds and learn how towers stack without risk. Apopalypse sends bloons without breaks, which forces strong early builds and steady control. Deflation gives a lump sum and no income, so you plan a full defense from the start. Extreme maps squeeze space and punish waste. You earn medals as you clear tracks and unlock tougher settings, then push freeplay to see how long your setup holds.
