Mars Client is the official modpack for the Mars Command Minecraft server: a curated NeoForge 1.21.1 experience built around Create, Create Aeronautics, collaborative engineering, exploration, and just enough questionable space-agency bureaucracy.
Build factories, transport networks, aircraft, rail systems, and increasingly unnecessary mechanical solutions with friends. The pack includes shared progression, proximity voice chat, quality-of-life features, server-side protection, and a growing Mars Command world built for long-term multiplayer play.
What to expect
- Create-focused gameplay: automation, contraptions, trains, logistics, and industrial builds.
- Create Aeronautics: take engineering above ground with aircraft and aerial infrastructure.
- Multiplayer-first design: shared projects, claims, waystones, voice chat, and community progression.
- Curated progression: major milestones are released through Mars Command protocols, keeping the server’s journey collaborative rather than a race to endgame.
- Quality-of-life tools: storage improvements, maps, backpacks, building tools, and polished client visuals.
- Mars Command atmosphere: Landing Zone 01, mission-control alerts, orbital protocols, and a persistent concern that the moon knows too much.
