About
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.

After beating a map that is literally impossible without an optional mutant you have to buy to get another move on the same turn, followed by a map where the enemy spams 10+ artillery, which can destroy any unit in 2 attacks and can do a multi tile attack every 2 turns, I think I'm ready to say this game isn't good. Some other complaints: terrain doesn't matter, it's the difference of about 5/100 damage in most cases. On launch the commander powers were extremely broken and are still kind of broken. Your flying mutants still get attacked by ground units but also get bonus damage to them by anti air, awesome! I've never had a helicopter last more than a turn or two because every map you get them, the enemies special ability is to spawn 5 of the alien equivalent (saucers) or.. They're spamming artillery and their artillery can 1 shot flying unlike mine which cannot attack air Overall this really is just a tech demo and made me want to play advance wars instead
This game isn't revolutionary, but offers a fun throwback to games like Advanced Wars with some clever mechanics with the mutations, which create interesting strategic opportunities. I got this game for a little under half off and for less than $10, this game is a steal. If you are a fan of games like Advanced Wars, this is the classic definition of a 7/10 game that you probably won't regret picking up. I'm very excited to see Relic trying smaller scope games and appreciate that they seem to be still providing some support for this game, including the recent Steam Deck verified patch, which finally convinced me to pick this up. I'm looking forward to seeing what Relic Labs does in the future.
Like the switch's Wargroove, this is mostly a copy paste of Advance Wars, which is old enough now a lot of younger gamer won't know it. the only part original to it is splicing beast-people. It's a change, not great, not bad, just makes it a little different. If you like AW and Wargroove mechanically, then you'll probably like this one mechanically. The maps aren't as refined though. as for story, it's low quality writing but i don't think many people buy this type of game for the story anyway. Bigger problem is the blatant anti-male bent to it. 100% of good ideas come from the obviously superior in every conceivable way female characters, who are actively derisive toward the male ones.
Very fun, tactical and surprisingly chunky (30 missions) for a side project. It feels like Unity of Command 2 with an Xcom/Invader Zim flavour to it. It sure is a shame barely anyone will hear about it unless they follow Relic's games. Keep cookin', Relic Labs!
Very Advance Warsy. Really good game. Cross between Advance Wars and Into The Breach to me. I you like turn based strategy with a reasonable cheesy Campaign that you can adjust difficulty for each mission if you find it too tough then give this a try.
I've been playing this on my Deck and having a blast. The best Advance Wars spiritual successor I've played. There were sudden disastrous performance issues on my Deck after a certain mission. Submitted a bug report. The most recent patch fixed those issues. So I like how they handle feedback and didn't just leave us Deck users in the cold.
I really enjoyed advance wars style games, and this is that with an old school, B-movie scifi asthetic. The spliced super soldier mechanics are fun and add needed unit variety to the game. My one complaint is an annoying glitch that happens on the end of turns when you only have your commander power remaining and you start an attack animation. This can soft lock a mission where you have to force the game closed, and if you haven't saved during the mission, you'll wind up starting over.
This is a great game! I enjoyed every minute of it. Challenging and engaging. Should be getting a lot more publicity and kudos than it is. One of my favorite new games.
Poor UI design and clunky mechanics that seem to be made by someone who never played strategy games before. Way too much dialogue for my taste, Way too much customizations and depth from the very beginning, I don't even want to know what comes later. I understand the idea behind them but I think are poorly implemented and the UIX for me was mediocre at best and lacks any sort of balance. Wasted 15 mins on dialogue, 5min on customization and 3min on gameplay fighting with the "wait" button. Yes you read that correctly, the cherry on top, to move you constantly have to click on a something that looks like dialog box that says "WAIT"! I don't find this to be anywhere close to previous games from RELIC in terms of quality. To me, it looks more like a cheap "mobile first" game designed to waste as much time as possible. Or maybe I'm just not in the target audience.
Not ready for prime time. Couldn't even get through the second campaign mission without the game freezing. Refunded. It has good bones, so give the dev a year or so to release a product that works. Also, I have the latest i9 with 128 GB RAM, 4080 Super, all of which usually stays quite cool which is why I was surprised to hear the fans rev up to max during a turn-based game with cartoon graphics running at 1080p. What could be taxing such a powerful processor to that extent in this game? Has to be something wrong with the game itself. Last - I had the delay to max and still found that battles occurred so quickly that it was nearly impossible to determine who was fighting and from which position. Game needs a lot of player feedback. Great concept, though.
