Airhorn

The Airhorn is a Tier 4 Tank upgrading from the Builder or the Foghorn at level 45. It fires blocks, which has a gun on the each side like the Foghorn's traps.

Design
The Airhorn has a circular body with a Builder guns on the front, and a short, and front gun-width trapezoid in the back. The design is similar to the 's.

Technical
The blocks are shot out slightly less frequent than the Builder does, and also lives shorter amount of time. The blocks receive no stat changes other than these. They have a gun on the each side that shoots bullets.

The bullets shot by the blocks, compared to the Foghorn's, has slower reload (Exactly takes 15/11x time to reload). Despite gaining one more gun from the Foghorn's traps, the DPS/ROF is very slightly reduced, exactly by 1/45x (Assuming that all of the bullets hit an enemy). There's no bullet stat changes other than the reload.

The Airhorn can have only 5 blocks at a moment. If the 6th block is shot, the 1st one will be destroyed.

As the Airhorn

 * Many of the strategies used for the Foghorn work.
 * As it can only have 20 guns for max (Fogforn can have 24), you should focus to attack your enemies by the blocks, not by the bullets.
 * Try to put the blocks in various angles, or between the obstacles. This will make the bullets spread, and makes the bullets hit more targets.
 * It is recommended to upgrade, as many of its upgrades are very formidable tanks. Using upgrading as a last resort in a fight may be able to catch opponents off guard.

Against the Airhorn

 * Stronger ammunition can easily destroy the blocks.
 * Try to destroy the blocks as soon as they're fired, so they'll be destroyed before they fire any bullets.
 * The bullets don't deal so much damage, but you should be careful, because massive amount of bullets can deal massive damage to you.
