Mutant Year Zero: Seed of Evil – PC Steam CD Key

In Stock - Limited stock available

$8.99

In stock

SeedofEvilis an expansion to the award-winning tactical adventure game Mutant Year Zero: Road to Eden picking up where the original game ended and offering hours of more gameplay, new locations to visit, and a new leading character! 

Continue the main story and explore many hours of all new content. Expand your team with the veteran stalker Big Khan the moose and get ready to defeat a new threat to Dux, Bormin, Selma and all the others. 

In Seed of Evil you must solve the mystery of the powerful and ominous roots which have taken over the Ark. Discover huge new maps, battle new enemies, improve your mutations, get your hands on all new gear, defeat foes trying to take back lost ground and face off against a vicious new adversary. 

To play Seed of Evil it is highly recommended to have finished the main story in Mutant Year Zero: Road to Eden, because of story spoilers and the level range of the new content.
Continue the main story
See what happens after the ending of Mutant Year Zero: Road to Eden. Continue into a new future for Bormin, Dux, Pripp and all the others at the Ark. How will they deal with what they have learned?
New mutant: Big Khan
You can now add Big Kahn the moose to your squad of mutants. He is a veteran stalker who has been exploring the Zone alone. He is not only skilled at doing critical hits but also has the unique mutations Ground Pound and Flame Puke, which make him excellent at dealing with groups of enemies.
Face a new threat
The Ark has suddenly become enveloped in mysterious roots and many of its inhabitants do not seem to be their normal selves. Even the Zone Ghouls appear to have been taken over by this new menace and it is up to your team of stalkers to set things right!
Hours of new content
Take on new enemies in places like the Hall of Electric Coffins and Mausoleum of Suburbia. The new story in Seed of Evil offers a host of new challenges and brutal fights. Get ready to rethink your tactics as you face off against brand new enemies.
Improve your mutations
Upgrade Bormins Hog Rush to Bear Smash for increased power and Corpse Eater to Corpse Feaster so that regaining lost HP no longer costs an action. Upgrade Duxs Moth Wings to Wings of the Sniper which removes all range penalties.
Retake lost territory
Revisit places like the Spear of Heavens or Sea Titans as Zone Ghouls and police bots once again encroach upon places you have already cleared. This time they are stronger than ever!

Good to know

Frequently asked questions

How do we keep our prices so low?+
Two reasons. First, we buy at volume directly from authorised channels, which earns us wholesale discounts we pass straight on to you. Second, everything is delivered digitally — no boxes, no postage, no warehouse costs. That's how we sell the exact same official product key for far less than the retail price, without cutting any corners on authenticity.
Are our codes / keys real?+
Absolutely — every code is 100% authentic and sourced from authorised distributors. Your key activates directly with the official vendor (Microsoft, Norton, and others), exactly like one bought in-store. And if a key ever fails to activate, we'll replace it or refund you, no questions asked.
How long does it take to get my order?+
Most orders land in your inbox within a few minutes of payment, any time of day. Occasionally an order is flagged for a quick security check to protect against fraud — if that happens, we may ask you to confirm a detail, which adds a short delay. If your order takes longer than expected, just reach out and we'll sort it fast.
Do we ship by post?+
For software keys, there's nothing to post — your code is delivered digitally by email, worldwide, so there's no waiting on the mail. Physical hardware orders are the only exception: those are shipped within the USA.
How can I download / view my code / key?+
Your key and download link are emailed to you within 30 minutes of purchase — usually much sooner. You can also find it any time in your account under your order history. If you don't see the email, check your spam folder, and remember each order comes with a download link plus a step-by-step activation guide.
Are there subscription fees for your product keys?+
None. Our Windows and Office keys are a one-time purchase — you activate once, own the product key for good, and never pay a monthly or annual fee. The only products with a term are genuine subscriptions like Microsoft 365, which are always clearly labelled with their duration on the product page.
Can I redeem / activate my product key later?+
Yes — the key itself doesn't expire, so you can hold on to it and activate whenever you're ready. That said, we recommend activating fairly soon so you can confirm everything works while you're still within our money-back window.
I don't know how to activate my product key!+
No problem — our Help Center has detailed, step-by-step tutorials for every product, with screenshots to guide you through each stage. If anything still isn't working, our support team is on hand 24/7 and will happily walk you through it.
