Beam tower

The Beam tower is a pretty expensive tower that blasts 285px beams at bloons.

The beams are also 10px wide.

The tower itself is 30 pixels large and is a land tower.

The beam is fired once every second and only deals 1 damage, but makes up for its massive popping power, as the beam can inflict up to 80 bloons!

Strength: Lead bloons and grouped bloons.

Weakness: Purples
