Castout, you have a PM with my feedback (for not being spoiler).
I did not bored with the mission. I love the long ones, with a lot of previous planification and many choices to choose from.
I didn't sank the frigate, only fired a torpedo with presets under it to avoid sinking, but forcing her to runaway.
(but the got sank by a helo
)
Took me two real days (I didn't used maximum time compressed, only the previous one).
