Bloons TD 4 Expansion is a tower defense game in which balloons follow a fixed path and you stop them by placing monkey towers beside it. It is a companion to Bloons Tower Defense 4 from Ninja Kiwi: the towers, upgrade system and escalating rounds work the way they do in the main game, but you play on a different set of tracks. That makes it a natural next stop for anyone who has worked through the main game and wants new layouts to solve.
A session is a run through one track. You start with a small budget, place a few towers, send the first round, and spend the money each popped balloon pays out on more towers or on upgrades. Early rounds are easy. Later ones bring faster, tougher balloons, and the big MOAB-class balloons mean a weak defense gets overrun. The page runs the original Flash build through Ruffle, so it plays in the browser with nothing to install.
How to play
Choose one of the expansion tracks from the menu. Everything is done with the mouse. Click a tower in the bar, place it on the map, and press Start Round to release the next wave of balloons. Click a tower you have already placed to see its upgrade options and spend your cash on them.
The core decision each round is whether to buy another tower or upgrade one you already have. A new tower adds coverage. An upgrade makes an existing tower pop harder, faster or from further away.
Tips
- Study the path before you spend anything. Towers near a bend or a spot where the track doubles back get more shots at each balloon than towers on a long straight.
- Put your first towers where they cover several stretches of track at once, rather than at the very start of the path.
- Keep some cash in reserve. Upgrades usually beat piling on cheap towers once balloons get tougher.
- Do not rush the Start Round button early on if you are not ready. Place and upgrade first, then release the wave.
