Mass Effect's free DLC (on the PC at least) Bring Down the Sky, adds a new system right by the Citadel, Local System and the starter planets of Feros and Noverria.
Is it possible/realistic to play this DLC straight away as a starter character, or should I wait until I've levelled up a bit? If so, what level will it still be a challenge at? I don't want to come back to it at level 50 and find that I can just stroll through it without a challenge.
Is there a rough range of levels where this is possible but still a fun (rather than frustrating) challenge?
