My characters are not skilled specifically for STFs. However, if a new player to STFs is good at listening and following directions, then I can help them to complete Infected in about 2 1/2 hours. Both Voru and Jeren are Tactical officers. The player roster is less importaint in Infected compaired to The Cure or Khitomer. With a Klingon team, we were all Tacs and cleared it in about 3 hours. I was a newbie once, and am glad to help others get past this first STF mission.
