Build a colony on a fungal alien world and keep it alive. Survey the fog, claim the ground under it, and send wardens against the feral packs the blooms spawn before they reach your land. Each map is a new colony to hold, and a campaign takes you from first landing to last stand.

About This Game

Xenobiome Command is a strategy game about keeping a colony alive on a fungal alien world. Each map is a new colony. You land in the fog with one colonist and have to grow from there.

The purple ground on every map is bloom, and bloom spawns ferals. Packs walk out of it toward your Landing Zone and take any area they reach. If they take the Landing Zone, the colony is lost. Clear a bloom and it stops spawning. Kill the nest and the cleared blooms become ground you can claim.

The Directorate funds you and watches your Command. Finish quests to earn Command. Lose colonists or miss deadlines and Command drops, and at zero you're recalled.

  • Survey the fog to see what's out there. Every survey costs Vigor, and distant ground costs more.

  • Claim areas to harvest Biomass, Filtrate, Fiber, and Heat Cells, then refine them into Medicine, Regolith, and Alloy.

  • Build 43 structures, from sleep pods and orchards to labs, forges, and shrines.

  • Recruit wardens and march them out to meet the feral packs. A fight lasts several days, and you can retreat whenever you want.

  • Watch the packs move. Sleeping packs send raids toward your areas every few days, and a pack you wake attacks at once.

  • Incidents, blights, and the cold months of the Drift get in the way of every plan.

  • Pick a commander and a colonist trait before you land. 18 commanders and 7 traits change how a colony develops.

  • Draft from 14 technologies across 4 research tracks, so your toolkit changes from colony to colony.

  • Face 140 incidents and colony events, including 41 core incidents with choices that carry a cost.

  • Artifacts, festivals, and stars carry progress from one colony to the next.

  • Every map records the hardest difficulty you've cleared, and commanders earn titles as you play them.

Play 2 campaigns across 27 handcrafted story maps. The Foothold campaign runs from first landing to last stand. The Carrion campaign follows a faction that lives off what it kills. Narration plays between maps, and every campaign map hides one secret.

Scenario mode replays 24 biomes with seeded layouts, 16 rolled map traits, and 4 asymmetric factions. Today's Drop is a new seeded scenario every day.

An interactive tutorial walks you through your first colony, and the in-game codex explains every system.

  • A map takes 10 to 30 minutes and saves when you quit.

  • Pick a pace from relaxed to sandbox, and pause whenever you want.

  • Choose from 4 difficulty levels.

  • Cancelled builds refund in full, and you can undo your actions.

  • Play with mouse and keyboard, gamepad, or touch, and rebind the controls.

  • The game works fully offline. Steam demo saves carry into the full game.

  • Buy once. Every future update and DLC is free.
