Requirements: E--, M4, C--, EX2, EL2, A--

The Gun Array System is an automatic ion pulse cannon platform whose sole purpose is to defend Asteroid Bases. Due to the relatively small crews working at these installations, the Alyssian military needed a self-contained weapon that had a long lifespan, and required little maintenance. The Gun Array System, with four turrets armed with a single PS13, is the result of this work.

Requirements: E4, M4, C--, EX--, EL2, A--

This Asteroid Base defense upgrade replaces the PS13 IPC with the Beam Array ion beam cannon, a substantial firepower upgrade for a commensurately substantial upgrade in cost due to the sophistication of the tracking system and the power plant upgrade necessary to operate the beam weapons.

These elite warriors are specially trained to board disabled vessels and return them to the nearest base, where they can be inspected for the presence of useful technologies.

Requirements: None, comes with the Troop Transport

The Commando Pod transports Commandos from the Troop Carrier to a disabled enemy vessel. A small and fast unit, it is quite capable of avoiding enemy detection � an absolute necessity if the Commandos are to complete their task.

Requirements: None
