About Earth vs Mars
Martians have been visiting Earth for decades, abducting animals and humans and harvesting their atomic essence to create bizarre Martian-creature hybrids. This time they’re here to claim our planet.
In this turn-based strategy game, an unlikely group of commanders will lead Earth’s military as they face an overwhelming Martian invasion. Fight high-tech saucers, grav-tanks and elite alien warriors in a battle for the planet’s survival.
Your secret weapon is the “Splice-O-Tron". With it, you can combine human "volunteers" with Earth creatures to create powerful hybrid supersoldiers to fight alongside Earth’s regular military.
Rain acid from the skies with the fast-moving cheetah-fly. Charge through enemy lines with devastating human-rhino hybrids. Or strike from the forests with your deadly squirrel-cow infantry.
As the campaign progresses, you’ll unlock new types of creature, powerful unit upgrades and game-changing commander abilities. But as your army evolves, so will your enemy’s, and you’ll face everything from the sentient organic weapon known only as “The Creep” to the Martian’s own mutant creations.

Earth vs Mars is our first game under the Relic Labs banner. Relic Labs games differ from our traditional, larger-scale strategy titles (which we're continuing to support and develop) in that they are created by smaller teams with shorter development cycles and a goal of experimenting in new strategy spaces, creating fun new worlds, and getting them in the hands of players sooner. Earth vs Mars was made by a small team of passionate Relicans with the goal of paying homage to some of our favorite strategy games, while adding a Relic twist.
How much does Earth vs Mars for PC cost right now?
Earth vs Mars for PC starts at €5.98 (€6.46 with fees) at Key4Games, 54% under the €13.99 (no fees) of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €13.99 (no fees) at Steam.
That €5.98 (€6.46 with fees) already includes the GOCDKEYS16 coupon, so apply it at checkout or the store will show you a higher price.
Supply is thin — 3 offers from 3 stores — and thin supply keeps prices steady rather than falling.

Worked out from 350 daily records of the Steam Key for Earth vs Mars across 1 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
Are these stores safe to buy Earth vs Mars from?
One caveat worth €0.31 (€0.11 with fees): the €5.98 (€6.46 with fees) at Key4Games is the cheapest, but that store carries only 37 Trustpilot reviews, so there is barely any track record behind it. Difmark sells the same shared account for €6.29 (€6.57 with fees) — €0.31 (€0.11 with fees) more — backed by 14.2k reviews and a 4.1 out of 5, which is a small premium for a seller thousands of buyers have already tested.
Which Earth vs Mars format should you buy?
With the shared account at Key4Games you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Steam costs €8.01 (€7.53 with fees) more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
Can you activate Earth vs Mars in US?
All 3 offers are Global, so the code redeems on any account no matter where it was created.
