SpaceSlog is a challenging and unique spaceship and colony simulator that focuses on shipbuilding, crew interaction, exploration and survival. Inspired by games such as Rimworld, Starship Theory, Dwarf Fortress and X-COM, as well as iconic media such as Firefly, Stargate Universe and The Expanse.
Your colony ship is destroyed, and with it humanity's final hope is lost to the dark, cold void. But somewhere, deep within the slog, drifts a barely functioning life pod. Alone, hungry, and lost in space, you command a motley crew of ragged survivors and must guide them through a time that has come to be known as the SpaceSlog era.

Whether you want to build a small but nimble ship with a small crew, or a large battleship with lots of crew, the choice is yours. Just ensure you have enough supplies to manage your crew and keep your ship functioning.
Careful consideration must be used when placing doors, power or atmospheric systems in case of breaches or other hazards.
Each time you play, the game's incident system will generate a different galaxy for you to explore. Whichever difficulty you choose will influence how this galaxy or incidents are generated.
Stay in one place for too long or get stranded and your crew will surely die. You must keep moving and find other ships or factions to trade with in order to survive.
The needs of your crew must be met in order to keep your ship fully functioning. An angry crew may rebel, decide not to work or give up completely. Ensure you have enough food and water to feed your crew. You must also choose your captain wisely.
Gear up and fight different species of aliens in melee or ranged combat. Cut off their limbs and allow them to bleed out so you can harvest their meat for food and skin for furniture. Build a medbay to heal your own sick and injured crew.
All the game's data is stored in JSON files. This means it is extremely easy to change anything currently in the game and even add new ones. In the future we plan to expand on this even further.
The author of SpaceSlog has spent over 10 years painstakingly developing a large and popular free modification for Mount&Blade Warband called A World of Ice and Fire. This is the reason for wanting extensive mod support and should hopefully give peace of mind for anyone wanting to purchase SpaceSlog, knowing the author is dedicated and willing to finish a project.
