Spiritus Astrum

Spiritus Astrum is a persistent, open-world roleplaying sandbox with multiplayer support. You can explore an infinite, procedurally generated universe, travel between realistically scaled solar systems and planets, and land to explore, craft and build. Play alone, with AI companions or with other human players.

Explore and build

Travel aboard a variety of spaceships, vehicles and tools, and spend time exploring vast worlds or living in densely populated cities. You can purchase apartments and land, build homes, and own ringworlds or entire planets. Solar systems, stellar phenomena and planets are realistically scaled.

Shape your character

Customise your character’s appearance, choose traits and select a background. Possible backgrounds include trader, diplomat, explorer and war veteran. The game also includes life simulation: you need to eat, drink and sleep, as well as train your skills. The dynamic skill system means over-training some skills reduces others, preventing the kind of grind often found in games of this type.

Interact with the universe

Randomised NPCs, quests, enemies and resources support emergent gameplay. Your actions and choices affect how NPCs and factions perceive you. An NPC who likes you may join your crew or offer a discount on store purchases; one who dislikes you may refuse to talk to you.

Combat is optional. You can also use diplomacy, trading and stealth, and player-versus-player conflict is not allowed. Players can work together to explore or build, in a cooperative roleplaying environment.

Create your own life

You can spend your time travelling among the stars, settling in a city or exploring worlds alone or with AI or human companions. The game’s tools are planned to support creating and sharing stories, as well as making custom enemies, weapons and items.
