MarsX v3 - Musky Edition

This mod is a full conversion of Rimworld into a Mars colony builder

To continue playing this mod you can switch to the A16 branch of Rimworld, to do this you right click rimworld in the games library and go properties > betas then pick A16 from the dropdown, let it redownload the game and then you will have to disable any mods that were updated to A17 or just run MarsX on its own.

I'm currently working on Rimatomics which should be out soon, once thats done and the major bugs are ironed out i can get back to working on updating MarsX to A17 with lots of improvements and focus on adding more over the summer.

Description of MarsX
You can build and manage a fleet of refuelable ships that can travel between Mars and Earth.

The atmosphere, air and water are all simulated. O2, CO2, Pressure, Humidity, You must balance everything and maintain a constant supply.

There are new weather conditions like dust storms which block the sun and cover solar panels with dust.

Many more things have been changed such as backstories, skills, needs, food, resources, materials and much more.

I am working on a wiki and youtube series to help explain how everything works. But for now the way i start a game goes like this

1:Eject hab, moxie, tools and some food from the crates
2:place the hab and moxie, run power and gas pipes from the ship to the hab, once habs finished place air outlet inside to rapidly fill it with air from the tanks on the ship.
3:build beds and suit stations, make an area inside the hab and set the zones and rest mode on the suit stations and haul some essentials inside the hab like clothes food and wet wipes.
4:make some solar panels a stonecutting table and smelter, make a greenhouse extension to the hab with stone walls and start mining bauxite and iron to make steel and aluminium.
5:double dig a patch of sand to remove the top layer of icy sand and a second layer of dry sand and start making soil at a soil worktable.
6:when the greenhouse is ready place all the soil, then install skylights then irrigation pump, then pipe water to the pump from the ship.
7:build a miwex to produce water from the icy sand, and start working on sewage system before the wet wipes run out.

Then you start getting into managing your fleet, planning your cargo, and starting up fuel production to refuel your ships.

Surviving Mars also tries to have stories but after my colony was going the ony interesing thing to happen was The Final War mystery. Rimworld makes it's own stories and your mod made Rimworld Mars stories. Dust storms? No dig deal in Surviving Mars, I have plenty of oxygen storage. MarsX duststorms have me cleaning solar panels to try to get enough power to keep one heater going to try and keep one room above freezing. A room that isn't my greenhouse so all my crops are dead.

Great work, I can't wait for the next version.

In MarsX my inner airlock blew taking out the polymer hab wall. One of the astronauts was making dirt and almost died before getting into her suit. Luckly I patched the wall before I lost pressure in my green house. She had just become lovers with one of the other astronauts and eventually they got married. In Surviving Mars a meteor hit a dome. I patched it with some polymer that I hauled there several sols later after my materals gathering rover was done getting some metal. I lost some oxygen. No one died.

So, you've done a better job than a full studio with this mod. Surviving Mars and MarsX have different scopes and aims, but share many systems. I need food, air, materials, water, and colonist in both but the struggle is more real in MarsX. Surviving Mars tries to make me care about my colonist but I don't. Oh no, my last founder died... Who was he? She? Other? A suicide? The dome is overcrowded. Suffocation? Moron walked between overcrowded domes for no reason.

@JoeDaTomato No problem ^_^ I completely forgot to post it again, although it does seem to be a release version release at this point.

I liked his selling pitch ... "you'll pay a lot of money and there's a high chance you'll die."

Sign me up, Musk!

Nah Musk still says 2022 first mars mission (which I doubt, at least 2024), he said 2019 for first BFR mission - and it will not go to mars - he wants it to return to earth.
