Xeno Shell

"Reinforced shields that defend against Alien based weapons, but are weak to other sources of damage."

General
The Xeno Shell is a ship shield that is highly resistant to Alien Damage, but takes increased damage from other sources. It can only be used on Altairian Hulls.

Advantages
Like the previous shells, Deflector Shells have excellent shield energy and mass efficiency, even greater than that of the Harmonic Exophase Shield.

The Xeno Shell is able to resist Alien Damage, making it the second shield to do so after the Harmonic Exophase Shield.

Disadvantages
Xeno Shells take increased damage against all other damage types, making it only marginally effective against players who equip their ships with xeno weapons.

As Most Altairian Hulls already have a large amount of Alien Resistance, there is little need to add extra defense by using this shields.

Trivia

 * Hulls with active Xeno Shells glow bright green.
 * Interestingly, this and the Plasma Shell are the only Shell shields without any special attributes. This is likely because they resist a damage type that is less commonly seen.
 * The Xeno Shell was granted immunity to Alien Nebula Fields in the late April 2019 update.
 * Xeno Shell has received immunity to Plasma Nebula Fields in the early November 2019 update.
 * Its repair time was nullified as a result of the late September 2020 update, which updated the repair time of all Tier 7 ships to be invariant to equipment.
