Inertial nullifier

Inertial nullifier is a ship special in Master of Orion.

Description
The Inertial Nullifier creates a weakened hyperspace travel field that does not translate the ship out of normal space. This reduces the effective mass of a ship to almost zero, increasing its mobility and making it considerably harder to target. As a result, this adds bonus to the Ship Defense against beam weaponry. In addition, the ship can change direction (rotate in combat) without any movement cost at all.
