Really, if you think about it, the ocean is basically space, but more blue. I mean, both are sorely lacking in breathable air, give us the ability to defy basic physics while shouting “wheeeeee,” and are absolutely, positively, I-really-really-hope teeming with life. (What if fish aren’t real?! Wouldn’t that be a total bummer?)

Also, Mass Effect 3‘s now claiming that both have Reapers, and I suppose it would know. So now the hunt for Leviathan is on, and you can watch a trailer of some strange bald man wearing Commander Shepard’s clothes take the fight to the ocean’s briniest depths in a trailer beneath the break’s, er, briniest depths.

The DLC takes place before Mass Effect 3?s oh-so-controversial ending and – if you play through it and then make a mad dash for the credits yet again – apparently even adds to it. Here’s BioWare’s official line:

“Mass Effect 3: Leviathan expands upon the events of Mass Effect 3, with gripping and emotional storytelling, compelling new characters, and powerful weapons and upgrades. Discover more about the origins of the Reapers as you race across the galaxy to find the Leviathan. Travel to new systems, wield the AT-12 Raider Shotgun and M-55 Argus Assault Rifle, and unravel the dark history of the Reaper Race before it is too late.”

It sounds interesting enough. And while I’m incredibly impressed with the amount of multiplayer support BioWare’s been throwing Mass Effect’s way, single-player’s still the main attraction. Plus, I actually really dig the idea of episodic Mass Effect content. I mean, Mass Effect 2 – which actually had my favorite story structure of the entire series – was basically a series of character-driven episodes. Given BioWare’s general style and focus on gradual character development, I thought it made for far more compelling, relatable characters and believable plots than the tried-and-tired “urgent quest to prevent the apocalypse” shtick.

But maybe that’s just me. Maybe I’m all alone in the universe.
