Road Spikes



''Place these road spikes on the track to pop bloons. Can pop 10 bloons before wearing out. Road spikes only last until the end of the round.''

- BTD4 Description

 Road Spikes is a roadblock that made their debut in Bloons Tower Defense 2 and have been in every subsequent BTD game since. Road Spikes are a group of spikes which pop up to 10 bloons upon impact. Road Spikes only last until the end of the round. In BTD3 there is a number indicating how many spikes are left. Each spike pops 1 bloon (red being 1, blue being 2, etc.). Road Spikes will disappear at the end of the round if not completely used up. Road Spikes cost 25 on Easy Difficulty, and 30 on Medium and Hard. The prices are the same for every game that Road Spikes are in. In Apopalypse Mode Road Spikes and Monkey Glue last for an indefinite time since there are no round endings. Road Spikes are best used for popping Bloons that escape your defenses because they don't earn enough money used to purchase it.

Strategies

 * If you have to pop many Bloons with Road Spikes that is a sign that you need to improve your defenses.


 * Only use Road Spikes when you have to as they don't return the cost used to buy it.


 * As stated above they are best used to pop escaping Bloons only.
 * Popping Zebra/Rainbow Bloons and above is ineffective.
