Playing A Game Mass Effect 3: Leviathan PC

Leviathan taps into a theme that Arrival just hinted at: Reaper research leading to a dark place. Leviathan takes that ball and runs with it all the way into cosmic horror, shades of Event Horizon territory.

So while it may not have the strong characterization of Omega, it's got plenty of intrigue and tension to go around. The final mission is masterful in how it builds toward and reveals the mystery you've been chasing all along.

And the narrative payoff from this scene is one of the most memorable bits of the franchise.

Leviathan gets credit not only for adding meaningful background to Mass Effect's overall plot, but also for great pacing, scene-setting, visuals and voicework delivering a dark sci-fi thriller tale.

Better than: Mass Effect 3: From Ashes
Not as good as: Mass Effect 3: Omega
Seriously: Leviathan's lore revelations enrich the entire Mass Effect story.

Rating: Good
