Huge cannon, which fires slow-moving plasma-charged projectiles. Rounds are highly effective versus armor, and obliterate any hull structure left underneath.

A feared weapon platform, rarely deployed due to the complexity involved in manufacturing a built-up barrel that can safely fire enormous high-explosive shaped charge rounds. When such a shell impacts a target, the Neumann effect causes the warhead to propel a jet of molten metal into the target's armor, vaporizing a small area, causing hull breaches, depressurization and extensive internal damage from the spall.

–In-Game Description

The Hellbore Cannon is a large ballistic weapon firing high explosive shells. It has the lowest OP cost of any heavy weapon in the game and is generally unmatched in the anti-armor role against large targets. At the same time, the slow turret turn rate, rate of fire and projectile velocity leave it ineffective against smaller targets.
