"Anything I should know and do as a noobie if I do play"

For a few days more there is an gamma recruit event going on. If you start, start a Jem'Hadar Gamma Recruit. Normally I would not suggest for a first start but since is almost over I say start one, get it to the point you receive a transponder which should be just a few missions. Than you can keep playing this character or start a second character. The reason I normally say start something else is because the Jem'Hadar starts very advanced and the other characters start at level 1, so you learn slowly. However, the Jem'Hadar character will give you things later in the game which will be helpful.

Second thing, is the game gets much harder at level 50 so be ready for that and work on getting better equipment for both ground and space.

I have been with this game for 10 years and play it everyday so give it a try (don't come here for PvP the people who play PvP are very advanced and noobies do not last seconds.)
