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.

Overall use
Billboard albeit is not a terrible barrel as of right now, but it does provide good scrap production and can force the adversary to build a Shooting Box if you send at least a few of them to do so.

It's mostly outclassed by Lurid Layered because of how OP Lurid is in the game right now.

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.
