Leviathan provides an interesting new chapter to the ME3 story, and it's clear that a good deal of thought and care went into both the narrative and encounter design, but it doesn't match ME2's best efforts, most notably Overlord or Lair of the Shadow Broker. The DLC provides some beautiful new areas to explore, answers questions and fills in some of the rich lore of the ME universe, and challenges the player with slight innovations during some stand-out action scenes. Still, with a misstep in revealing information too early and no truly difficult decisions to make, it's a little short and a little plodding for the price tag.
+ Strong writing and voice acting, and some interesting, challenging twists on combat scenarios
+ Suitably creepy and mysterious, and well-paced overall with several ups and downs
+ New weapons, a new power, and decent payoff towards the main plot
- Coming this late after ME3's release considerably lessens the impact of the events in Leviathan—I wish I could have played it on release
- Slower-paced "detective" work is fine at first, but once the player has exhausted the eye-candy and grown used to the mystery, sections can drag on
- Probably a little pricey for the value, especially when compared to past DLC
Commander Shepard's exploits, male or female, have sold millions of copies of their games in our universe, safe-guarded billions of aliens in theirs, and have made headlines in both by including the ability to punch out reporters mid-sentence and explore cross-species, same-sex, and even old-fashioned hetero loving with accompanying make-out scenes. The intellectual property has been much-loved and simultaneously reviled, most recently by the outcry over ME3's original endings.
