Anyone here had luck beating the option objectives on the Khitomer or Infected STF ground missions? I never even get close. It took a long time to beat the optional objective on the Khitomer space mission, but I finally did.
(Only at Normal Difficulty; beyond that seems impossible).
Yes, in part. Khitomer is easy.
It just depends on quickly taking out the big room asap and people knowing how to blow the generators.
Infected is a different matter. Never succeeded there.
You have to kill all Borg very fast, and be at exactly the right spots at the right moment.
The workers assimilating the officers are triggered by proximity and aggro in the rooms while the whole optional is on a 15 minute timer. There is no margin for error at all.
