Marsward

Marsward

Marsward is a Minecraft survival mod about leaving Earth, landing on Mars, and turning a hostile red world into a place you can endure.

Craft a Rocket Kit, launch from the Overworld, and arrive on a custom Mars dimension with rusty regolith, basalt, ice deposits, dry riverbeds, crater basins, highlands, rifts, and buried places worth exploring. Mars is not just a reskinned Overworld: exposed water, open flames, ordinary farming, and careless exploration all stop making sense once you are there.

Note: Java version can be found here.

What You Do

Start on Earth, gather materials, build your rocket, and bring what you need for the first trip. Once you land, survival becomes a loop of exploration, mining, power, water, food, and range management.

Mars pushes you to build systems instead of relying on vanilla shortcuts:

• Mine Martian stone, regolith, basalt, iron oxide, and ice ore
• Convert ice into usable water
• Power machines with solar panels and batteries
• Grow Greenhouse Greens from Seed Culture
• Extend your EVA range with Habitat Cores, Route Beacons, and oxygen support
• Use Work Lights instead of torches or fire
• Navigate daytime dust storms and nocturnal alien threats
• Explore abandoned caches, rover sites, lava tubes, old lakebeds, rifts, and buried ice pockets
• Build and drive a two-seat, battery-powered Mars Rover with persistent cargo storage
• Witness rare meteor impacts, recover Meteorite Deposits, and smelt their fragments into iron

Features

Rocket Travel

Build a rocket on Earth, launch to Mars, and return using the same rocket system. Rocket placement and landing are tied to where you start, so Mars travel feels connected to your Overworld base instead of sending everyone to one fixed location.

A Harsh Mars Survival Loop

Mars has EVA limits, dangerous exposure outside safe zones, daytime dust storms, and restrictions on things that should not work in open Martian air. You can survive, but you need infrastructure.

Dust storms shut down solar generation, increase EVA drain outside safe coverage, slow exposed players, and push Route Beacons into storm-navigation duty so you can find your way through the haze.

Machines and Base Building

Marsward adds practical survival blocks and items, including:

• Habitat Core
• Solar Panel
• Battery
• Water Processor
• Water Tank
• Oxygen Generator
• Greenhouse Lamp
• Greenhouse Tray
• Route Beacon
• Work Light
• Reinforced Window
• Habitat Panel
• Airlock Door
• Field Manual
• Rover Kit
• Meteorite Deposit
• Meteorite Fragment

Machines use visual indicators so you can read their state in-world instead of relying only on chat messages.

Mars Hostiles

Mars suppresses normal vanilla mob pressure and replaces it with a Mars-only green alien. Aliens spawn at night away from the initial landing area, attack with visible laser projectiles, and clear out at daybreak.

Exploration-Focused Terrain

Mars terrain is built around red dust plains, broad highlands, dry channels, lakebed-like basins, basaltic regions, rift edges, craters, buried resources, and deeper underground areas. The goal is to make exploration and mining feel useful, not decorative.

Mars Rover

Craft a Rover Kit and deploy it on Mars to explore farther from your base. The rover carries a driver and passenger side by side, includes nine persistent cargo slots, and consumes stored charge while moving.

Park it unoccupied near a powered Habitat Core to recharge through the existing solar-and-battery network. If the rover is destroyed, its cargo drops and the vehicle returns to a Rover Kit.

Field Manual Included

A Field Manual is included in-game to explain the main survival systems, early goals, machine usage, and Mars rules without spoiling every discovery.

Recommended Play

Marsward is best played in survival on a fresh world.

Your first goal is simple:

1. Gather materials on Earth.
2. Craft a Rocket Kit.
3. Place and enter the rocket.
4. Launch to Mars.
5. Establish a foothold before your supplies run thin.

Notes

Marsward is built as a Minecraft Bedrock add-on using scripts and custom content. Because it changes survival rules and world behavior, it is recommended to start a new world for the cleanest experience.
