Under A Hostile Sun

New raw / unedited playtest footage:  Hostile Sun RAW Playtest - Explosive Atmosphere

Revised GM Guide coming 10/2025.  Follow the Development of Under a Hostile Sun on the Martian Society Discord!https://discord.gg/RbA7hhrEY5

The settlement’s life support is at the brink.  A solution to this world’s dangerous conditions must be devised & corruption amongst the station leaders must be investigated. But the Void of Space was not meant for Man. These planets are not “Mother” like Earth – you are under a hostile sun.

• A rules-lite exploration-focused RPG.  There is no combat system - rather the enemy is the brutal environment you are trying to survive in.
• Rules light but exciting system for Environmental Encounters that encourages risk vs reward decisions.
• Currency system that allows easy tracking of resources mined from the planet.   Find alien creatures to produce even rarer resources - maybe even the Prime Matter- unlimited potential- itself.  
• Play mat allows for resources to be easily tracked with Poker Chips or coins.  Just place the chips over the corresponding resource picture.  
  
• Illustrated with Adobe Fresco/Photoshop/.  A redesigned book done in Adobe InDesign coming soon.

The galaxy recently had a great upheaval.  Now many, seeking to escape corrupt local governors and war-ravished worlds, are desperately taking to space exploration.  It's a hope for a better life.  But at a cost.  The planets explored will include environments not easily inhabitable - volcanic hellscapes, colossal storms, radiation and more.  But with some grit, and a firm faith in the Immutable, maybe, just maybe, you and your brave team of settlers will be able to survive and greet the alien sun, not as an existential threat, but as a friend.  

As playtesting goes on, rules will be updated.
