About Stacks:Space!

Stacks:Space is a space-themed base builder card game with rogue-like elements. Buy booster packs to get new cards, discover craft recipes by stacking cards together, create structures, manufacture drones and droids, defend your base from enemies, visit distant planets, and more!

DISCLAIMER: This game is inspired by Stacklands, but it is not Stacklands, and it is not a sequel to Stacklands - it is a completely independent project that feels and plays differently from Stacklands.

Options and Features


  • Created with Stacks:Engine, a card game framework that is heavily inspired by the Stacklands and Cultist Simulator games
  • ~370 cards to collect and use in Stacks:Space (~370 cards in Stacks:Village mod)
  • ~100 craft recipes (some cards could be crafted via multiple recipes)
  • 7 unique bosses to defeat
  • 1 base location + 12 visitable quest locations (incl. shops)
  • Astronauts / Settlers have trainable attributes: Strength, Agility, Endurance, Intelligence
  • Various scenarios - each having different starting conditions, different end-game goals, or even a different location
  • Game Tutorial included for the first scenario
  • Daily Challenge Mode - an option to have a relatively quick game run with random goals and restrictions each day
  • Modding support

Combat



Both ranged and melee combat modes are supported (no combat box!). Melee units will move toward the enemy as soon as they see it. Drag your card next to an enemy card (do not stack them!), and you'll see them punching each other. Ranged units will shoot their projectiles immediately.
  • Stacked cards - the ones doing crafts - do not engage in combat, but could be attacked by an enemy card.
  • Some enemies prefer to attack resource cards instead.

Modding support



Stacks:Space is moddable! The built-in mod management interface allows near-infinite extension of a game. With just a tiny bit of JSON knowledge, it is possible to create and add new cards, recipes, scenarios, locations, and even completely new games. This game is so moddable that it already includes Stacks:Village, a fantasy village sim, as a mod - accessible via the top-right corner of the starting screen. See this youtube video for gameplay details. The comprehensive modding manual is a work in progress, please stay tuned.

Stacks:Space! takes the familiar idea of card stacking and transforms it into a compact science-fiction management adventure built around exploration, crafting, survival, and colony development. Developed and published by Stacks:Engine, the game uses cards to represent practically everything in its world, including characters, resources, buildings, equipment, enemies, and locations. Its presentation may initially appear simple, but underneath that straightforward exterior is a surprisingly interconnected collection of systems that rewards experimentation and efficient planning. The central gameplay loop involves obtaining cards, discovering useful combinations, and stacking the correct resources together to produce new items. With hundreds of cards and roughly a hundred crafting recipes to uncover, experimentation becomes a major part of progression. Some items can be produced through alternative recipes, giving players additional flexibility when particular resources are scarce. Booster packs introduce new materials and opportunities, while successful crafting gradually turns a modest collection of cards into an increasingly sophisticated space settlement. Colony development pro…

Stacks:Space! is one of those games that sounds incredibly simple at first, but I ended up getting much more invested in it than I expected. I am basically building a space colony out of cards, stacking them together to discover new combinations while trying to keep everyone alive. I really liked how quickly the game turns a tiny collection of cards into something that starts feeling like a proper little settlement. The main mechanic is built around stacking cards together to create new items, buildings and resources. I can combine materials to discover crafting recipes, then use those new cards to expand what my colony can produce. I enjoyed experimenting with combinations because the game does not reveal everything immediately. There is a satisfying feeling when I discover a useful recipe that suddenly gives me access to a completely new part of the economy. Managing the colony adds another layer because I have to balance workers, resources and production while dealing with threats. Astronauts and settlers have different attributes, and I can train them as the settlement develops. I also have to manufacture useful machines and droids while making sure I have enough supplies to …

Yeah, It's OK. It's free but not as fulfilling as the other Stack game

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
