'FLAK' - Flak Cannon

Introduction
Long-range area-of-effect explosive cannon, intended for use against air targets. A large projectile hit box allows it to detonate when near a target, but also causes it to prematurely detonate when dealing with larger targets.

Usage
A fully upgraded FLAK can fire quite quickly and for a decent stretch of time, though its erratic scatter pattern makes aiming difficult. When employed against retreating targets, the rounds will often miss by a wide enough margin to nullify its proximity fuze.

Using the gun in a dogfight is also not recommended, as the rounds do not explode when used on any target under roughly 250m away due to a trigger delay that prevents the explosion from detonating too close to the launcher.

Slower moving aeros can, however, reduce the minimum effective range by maintaining a low velocity whilst firing, while faster planes can increase it accordingly — either way, it is a good idea to avoid flying into your own rounds.

Though the rounds do not explode on collision, the Flak cannon does posses limited ground attack capabilities. Its low damage and trigger delay make it difficult to use in a close-quarters situation, making it far better suited to targeting weak points where applicable.

The Flak Cannon offers a surprisingly technical array of traits to take advantage of, though its difficulty in use can make it a tough option to use. Perhaps its greatest strength is its ability to reliably hit fast targets strafing around the user, should they fall into the gun's minimum effective range.

Trivia

 * An odd quirk is its 'double blast radius' effect. Very often, though very erratically, the flak explosion will appear to damage the enemy twice in extremely quick succession. Whether this is a bug or a side effect of an intended function is unclear, but this "critical hit chance" is as lethal to enemies as it is to the player. Scoring a critical hit on a Carrier weak spot can, astoundingly, actually one-hit kill it.
