Mutant Year Zero: Seed of Evil, the downloadable expansion to last year’s surprisingly challenging XCOM-esque tactics RPG Mutant Year Zero: Road to Eden, is an expansion in its simplest, most direct form: there’s simply more of it. While Seed of Evil makes tweaks and changes to the original formula, they feel very safe and don’t do as much to evolve the gameplay as one might have hoped.
Picking up where Road to Eden left off, Seed of Evil advances the overarching Mutant Year Zero story but quickly pulls a bait-and-switch by diverting to a new, self-contained mystery where your party of mutant stalkers fights an army of plant-based clones threatening the last vestiges of humanity. While I got a bit of proverbial whiplash from the quick, jerky nature Seed of Evil wrestles out of Road to Eden’s cliffhanger ending, the story ultimately does a good job creating some new mystique in a world you’ve already explored.
