Whirlybird

The Whirlybird is a tier 5 tank that upgrades from the Smasher and the Dirigible at level 60.

Design
The Whirlybird has a Smasher body, and a rotor with 4 blades on it. It has a tail rotor, similar to the Dirigible.

Technical
The Whirlybird can continue to move in the direction that it was just moving in, even when the player is not pressing the wasd or arrow keys, like the Dirigible. It can be pushed by players, crashers, polygons, and projectiles. It can also fly through borders in Portal Domination. Like the Dirigible, the Whirlybird cannot go through portals, and is not affected by the portal’s pull, making this the only way of traversing the different sections of the map. The Whirlybird can fly over rocks, base protectors, portals, and dominators. Doing so will damage the Whirlybird. The Whirlybird also has an upgrade cap of 12, like most other smashers. The Whirlybird also has the same stats and upgrades as the Smasher.

Upgrades
The Whirlybird upgrades from the Smasher and the Dirigible. It does not upgrade any further.

Trivia

 * Like the Dirigible, the Whirlybird can never stop moving.
