Our Explorers hold all the necessary blueprints for efficient on-site mining operations and base building including Automatic Extractors, O2 Generators, Armories, Single-Barrel and Double-Barrel Automatic Defence Turrets, and the most important of them all, our Glorious Flag!A Campaign to Remember
The Masterful Invasion Plan we envisioned is divided in 9 Missions. Our conquest will be swift, sure, and certain! But, in case the pitiful Martians manage to put up a fight due to their sheer number, we are also prepared to entrench and endure an Endless warfare.It will be glorious! Mars, or Die!

BIG news from 34BigThings!
Privet comrades,This is the third time 34BigThings is being born.The first time is a story we’ve talked about extensively in the past, possibly because it’s been 13 years. The second time was when 34BigThings was acquired by the Embracer Group in November 2020. We didn't feel the need to communicate much on the topic at the time; after all, we thought, "This is a great chance to just focus on making games."If you’ve followed the gamedev ecosystem over the last six years, the next part won't surprise you. We were put under the guidance of Saber Interactive and were asked to scale up, to absorb more and bigger productions. Then, the business of making games became risky and costly. Through it all, we managed to stay afloat without slashing our workforce. Saber left. Embracer split. Natural spells of radio silence, shifting priorities, and changing contact points followed. Through this, we managed to concept, prototype, develop, wrap up, and launch Carmageddon: Rogue Shift AND something else that is almost ready (more on this later).The third time we’re being born as a company is today. Well, not exactly today: this technically happened in April, but it's much more dramatic this way.The next title we're going to announce SOON™. Seriously, it's one of the largest IPs in the world. We're absolutely thrilled about this one and we can't wait to show you.For now, keep an eye out for the Steam Summer Sale. Carmageddon: Rogue Shift will be 30% off!For more details directly from our studio head, Giuseppe Enrico Franchi, stop by our brand-new blog, your destination for all things behind-the-scenes on our journey in the future.Thanks to everyone who has stuck with us for all these years: our incredible staff, our fellow devs and studios, our community, and especially the players.-Team 34BT 3.0Read full article on Community Announcements (Vendetta)AnnouncementsOfficial

Mars or Die! gets amazing free content!
A total of 669 changes between V1.1.2 and V1.2 THE PEOPLE HAVE SPOKEN! The Supreme Leader was downhearted with the reception of its propaganda. After eating an unhealthy dose of chocolate, he called for a Great Warfare Maneuver to shake things up. After many fervent weeks of work, we are now ready to present the New Great Plan for conquering Mars! Of course, we will need to re-establish communications with our Explorers first... NEW DEFENSIVE STRUCTURE: BARRICADE To stop aliens from chewing on your defences, you’ve got to… give them something else to chew on first! These Titanium barricades with an integrated Energy Field can withstand terrifying amounts of punishment, allowing your turrets do their job. https://thumbs.gfycat.com/QuestionableFantasticChamois-size_restricted.gif NEW DEFENSIVE STRUCTURE: MORTAR TURRET Get rid of those pesky swarms from a distance! The Mortar Turret drops shells dealing AoE damage. Its long range also allows to counter aliens shooting from afar. A must-have gadget for every interplanetary army! https://thumbs.gfycat.com/MassiveBlaringBluefintuna-size_restricted.gif NEW DEFENSIVE STRUCTURE: STUN TURRET When it comes to hand-to-hand combat, every second counts. This revolutionary installation fires a strong audiovisual shockwave that overloads alien senses, dealing moderate area damage but especially stunning them for a few precious moments. https://thumbs.gfycat.com/SinfulAbsoluteGoral-size_restricted.gif UPGRADEABLE DEFENSIVE STRUCTURES A new Structures Upgrade System allows you to spend your Resources to strengthen your Turrets individually, up to level 10! From today, we won’t depend on crate-box supplies only! https://steamcdn-a.akamaihd.net/steamcommunity/public/images/clans/32884636/2cd47945256af7bd1217f79775a118ba9ed14ae7.jpg NEW ALIEN: BOMBER These strange, short creatures look like they just left Thanksgiving dinner. Problem is, they are basically mobile buckets of explosive chemicals. And, they run like stink! https://steamcdn...Read full article on Community Announcements (Drowne)AnnouncementsOfficial
