Leviathan is a much-needed addition to Mass Effect 3, and offers more than enough new content to merit the ten dollar pricetag. Squadmates finally interact during the scenes of the DLC and are no longer mute, and another aspect of the lore of Mass Effect re: Reapers and the origins of the Catalyst is revealed. There's tons of variety in terms of the enemies you will be fighting, and a few of the levels are especially impressive - that's right, *levels*. While I don't like the change in reference to the purpose of the Reapers that ME3 gave us, Leviathan does more than enough to add context and make this unfortunate change tolerable. It unfortunately doesn't change the ending significantly, which may make it seem worthless to those still scarred by that abysmal climax, but it is entertaining otherwise and adds a hefty amount to your War Asset total.

This review contains spoilers, click expand to view. Answers, precious answers. Leviathan addresses the gaps in the history of the Mass Effect Universe that the core fans have been pulling their hair out over. Namely, how did this begin. In so ways it gives more than From Ashes and in one way, it gives less. Specifically, there is no new squad member available at the end of this chain of events. There are however, new weapon mods, new weapons, a new ability, and a trophy for you Captain's cabin. But those things aren't what most are looking for. The gameplay and the story are rewarding. As for as the plot, it's tight, coherent, and rewarding. The adventure is only about 3 hours depending how involved you want to get. There are pieces of lore scattered in datapads that are well thought out. In typical Bioware fashion (Jessica Chobot not included) the voice acting is superb. While it doesn't quite have the same gravitas as Lair of the Shadow Broker, it's still an excellent addition and worth downloading. What I still remain curious about is whether this chain of events plus those still to come will expand upon the end came choices instead of just adding perspective.… Expand

This is fantastic dlc, equal to lair of the shadow broker. Its missions are extremely fun and are a fresh take on the mass effect formula and the story is great as well. For those who love Mass Effect this is a must have.

What is wrong with you people? Mass Effect (1, 2 & yes, 3) is one of the greatest games/sci-fi series ever! I'm wondering if those who continue to repeat the "ending sucks" mantra have actually played through with the extended cut. The EC answers all your questions...yes, for those of you to challenged to figure it out before. Levithan is a great little addition to the overall game and I enjoyed it very much. The battles were good and the end scenes were awesome. All of the whiners need to get over it...… Expand

Good game, cool new lore and some creepy new worlds. This does not change the ending to Mass effect 3 but it does give you some closure and much needed explanation.

The gameplay is fun and full of hire level monsters, music is good and new worlds are like I said, lovely.

The only Con is: does not change the ending but all and all it is a great addition to a great game!

this DLC answers pretty much ALL of the questions, and most of the rants here are about not changing the ending, I find that incredibly irritating, not because the ending is bad, the DLC is bad! the gameplay is solid and it may be a bit too short, but when you find Leviathan EVERYTHING is answered.
