Bring Down the Sky is a solid, at times intense start for Mass Effect DLC. It's better than many of the main game's side quests but, essentially, it follows the same format. Videogamer have high hopes for future, inevitable DLC - Bring Down the Sky offers an additional 50 Gamerscore points, leaving room for another four sets of DLC if they follow suit.
Next time though they would like to see something on a planet surface, on a greater scale and with more story elements - akin to one of Mass Effect's main story planets. That, and perhaps some more special abilities. That would be worth paying extra for.
