Coal (ScrapTD)

Coal is the sixth barrel in ScrapTD and costs 100 bricks to unlock.

Strategical use
Coal is a somehow good barrel, but almost nobody uses it. It's Alive has got x2 health points, but does normal damage, also costs more and is an air barrel. Even on level 1, Blue Laser on level 11 would need two hits, it can be greatly used like Swiss, but for Danger Zone.

It can be used as a bridge from Lurid Layered to It's Alive.
