Circle Blue (ScrapTD)

Circle Blue is the first barrel in ScrapTD and is automatically unlocked.

Strategical use
When the game came out, Circle Blue was a true killer. But it got nerved heavily and is practically useless right now, it's not a problem if some get to the base, because even on level 20 it does less damage than Square Pink or many other barrels do at level 1. The only sense in upgrading it is for getting xp.

In the lower arenas it is actually a bit stronger, because there are some which don't defend, but it can be defeated easily.

If a player with a high-leveled Circle Blue is seen (7+), the chance that the opponent started playing a long time ago is high.

Trivia

 * It was one of the first two barrels in the game, in the alpha, together with Square Pink.
 * Circle Blue, Mobile Delivery and Not Too Fresh are the only barrels which don't deal 50 damage at level 1.
