About Earth vs Mars

Earth vs Mars - about the game

Martians invade Earth to claim the planet after years of abducting humans and animals for atomic essence hybrids. Command Earth's military in this turn-based strategy game against saucers, grav-tanks, and elite warriors. Deploy the Splice-O-Tron to fuse human volunteers with creatures, unleashing cheetah-fly acid rains, human-rhino chargers, and squirrel-cow infantry. Progress through over 30 campaign missions to unlock new creatures, unit upgrades, and commander abilities as enemies evolve with mutants like The Creep. Challenge AI in VS Mode on custom maps, compete in 1v1 online multiplayer as Earth or Martians, or chase scores in Challenge Mode with the Map Lab. Strategy fans who enjoy hybrid units and tactical depth will find endless replayability here.

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.
