The final piece of downloadable content for Mass Effect 2, Arrival, leads directly into Mass Effect 3 and explained away some of the confusion I had after playing the demo for the trilogy’s finale.

Admiral Hackett reaches out to Commander Shepherd and asks him to undertake a rescue mission solo. An agent of Hackett’s has been working in Batarian space and has uncovered substantial evidence relating to the arrival of the Reapers. She has been apprehended by the Batarians however and is currently in prison. The Batarians and humans have a frayed relationship and if Hackett sent in a squad, this would cause turmoil; much like the relationship between the USA and Pakistan when a special forces squad took out Osama bin Laden. This relationship is why Hackett is asking Shepherd to go it alone. Hackett explains that it’s better for the operation to be viewed as the act of an individual rescuing a friend, rather than an act by the Alliance itself.

So, Shepherd sneaks into the prison and rescues Dr. Amanda Kenson and the two then battle their way out and back onto the asteroid that houses Dr. Kenson’s base. When they arrive Shepherd is shocked to see what Dr. Kenson has found – a Reaper artifact, and one that’s out in the open. Shepherd is immediately worried that everyone on the base has been indoctrinated as Saren had been in Mass Effect; Dr. Kenson claims that’s not the case and they begin discussing the importance of her find.

What Dr. Kenson has gathered relates to the Reapers arrival through the mass relays. Her crew had developed a plan to crash the asteroid her base resided on into the nearby mass relay, preventing the Reapers from entering the solar system. However, they had a change of plans because they had been indoctrinated. They overtake Shepherd who wakes up days later as his window of opportunity to save the day is shrinking. Shepherd proceeds to blast his way through the indoctrinated Alliance members until he reaches a lacking conclusion.

One of the hallmarks of the Mass Effect games has been the ability to shape Shepherd and the universe around him through key decisions. Arrival finishes in a way that seems (almost) ideal for a chance to make hefty moral decision but whimpers out, in spite of an explosion.

Arrival leads directly into Mass Effect 3 (despite the two year gap between games) and explains away my confusion over the soon to be released finale’s opening. Arrival is heavily combat skewed and not having Shepherd’s crew is pretty lame. It’s probably ideal to play Arrival to fully understand Mass Effect 3, but compared to the three other DLC packs for Mass Effect 2, it’s my least favorite. Plus I’ve explained much of the DLC anyways so go figure.
