Billboard (ScrapTD)

Billboard is the fourth barrel in ScrapTD and is automatically unlocked.

Strategical use
Billboard was the ultimate killer barrel when the beta came out. It got nerfed many times, becoming weaker and weaker. Right now it's still a pretty okay barrel, but while it got nerfed Lurid Layered got buffed, making Lurid Layered more useful right now.

Like Banana Hole it can greatly be combined with the abilities Faster Barrels, Clone and Freeze.

Trivia

 * When the beta came out it was the barrel with the second-highest player-kill rate, first being Not Too Fresh at that time and third Not Black.
