As laudable as proper single-player, story-driven Mass Effect 3 DLC is under any circumstances, perhaps BioWare ought to have reversed their schedule and prioritised this after release rather than multiplayer packs like Rebellion. Now most Mass Effect players’ universes have been long-saved, it’s a tad jarring to fly off on another mission set before the game’s climax. But yes - laudable, and soon.
Reads the Bio-blurb: “Leviathan expands upon the events of Mass Effect 3 with gripping and emotional storytelling, compelling new characters, powerful weapons and unique upgrades."
On this occasion, Shepard’s head is turned by yet another potential mega-weapon to use against the Reapers - the titular Leviathan - and there’s the promise of more on the origins of the combine-harvesters-gone-bad.
