In addition to setting standards for games' capacity to generate pure human joy, Mass Effect 2 has also mounted a pretty high bar in terms of post-release support. In the months since the game's January 2010 retail launch, BioWare has continued to deliver on mini-episodes that feel fresh, vital and fully realized.

Imagine my disappointment to find that the game's final episode, "Arrival," not only fails to top them all and send the DLC series out with a bang, but whimpers into its position as the weakest add-on of the bunch.
