The Phobos had no choice but to retreat.
Ves was fairly satisfied by the fact that the expert stealth mech managed to cripple the warp drives of at least one puelmer heavy cruiser.
However, despite all of the alien crew members that fell at the hands of an increasingly more outrageous spiritual fiend, the overall fighting power of the alien homeship likely did not drop that much.
Nosferatu had become so addicted at harvesting the lives of his alien victims that he completely neglected to sabotage any critical ship systems such as power generators and transphasic shield generators!
The Phobos could have done a lot more damage if the aliens did not employ so many effective and targeted countermeasures.
It was a pity that the arrival of so many alien starfighters made it impossible for the Phobos to linger around any further.
