Roadbuilder

Roadbuilder is a tower that places fake track on specific places on the background to stall bloons (MOAB class bloons are immune to this), but the road breaks every five rounds and needs to be rebuilt. Roadbuilder takes one minute to finish its first road, but rebuilds immediately. A second Roadbuilder creates a tollbooth that bloons take 1 second to pay for, which gives you 2 money. Every other Roadbuilder after that upgrades the tollbooth, increasing pay time by 1 second and money by 2.

COST: $1000

REBUILD: $750

Path 1
1. Better-Brand Concrete

Now uses a better brand of concrete, allowing to place road faster.

2. More Parts

Roadbuilder is able to spray icy foam on its track, slowing down bloons a little.

3. Even More Parts

A fire-engine ladder system allows Roadbuilder to create "highways" the next rebuild, stalling bloons for even longer.

4. Bloon Inflation Factory

Sometimes creates gray bloon traffic that dramatically slows down bloons.
