Exilium: Breeding Imperium

Build a colony. Breed a population. Conquer the galaxy.

Humanity’s last hope crashed on an alien world. As the commanding officer of the USS Frontier, it’s your job to turn wreckage into a thriving colony — and eventually, an interstellar empire.

Colony Breeder is an adult sci-fi colony management game built in Ren’Py, blending resource management, diplomacy, tactical combat, and visual novel storytelling.

 

🏗️ Build Your Colony

Construct facilities on a 4×4 colony grid — water collectors, farms, power plants, ore mines, barracks, shipyards, and more. Assign workers, manage production cycles, and keep the lights on. Every room matters.

 

👩‍🚀 Recruit & Breed

Revive breeders from cryo-sleep, each with their own personality, backstory, and mood system. Build relationships through conversation, raise affection, and breed to grow your colony’s population. Pregnancy stages, milking, and special protocols add depth to every interaction.

 

⚔️ Defend & Attack

Train marines, build auto-turrets, and fend off alien raids. When you’re ready to go on the offensive, load carriers with troops and invade enemy planets in wave-based tactical combat.

 

🌌 Explore the Galaxy

Build scout ships to discover new star systems. Encounter five unique alien factions — each with their own personality, diplomacy system, and military strength. Negotiate trade pacts, forge alliances, or declare total war.

 

🪐 Expand Your Empire

Colonize uninhabited worlds, establish outposts, garrison troops, and collect passive income from your growing territory. Conquer faction homeworlds to eliminate rivals entirely.

 

🔬 Research & Upgrade

Unlock tech upgrades through the Research Lab — faster production, stronger marines, automated defenses, reduced consumption, and more.

 

🤝 Deep Diplomacy

Five alien factions with full diplomacy: from hostile first contact to trade pacts, defensive agreements, and full alliance. Plant intelligence agents, respond to faction proposals, and navigate a living galaxy where factions fight each other too.

  • Real-time colony management with pause and speed controls
  • 6 unique breeders with individual stories and progression
  • Animated breeding sequences with multiple pregnancy stages

v0.6

This one got out of hand, in the best way. Almost every screen in the game has been rebuilt from scratch, combat got a full visual upgrade, and there’s a whole new relationship system with the breeders. Here’s everything that changed.

  • Each breeder now has her own affection level. It grows as you talk to her and spend time with her.
  • 🔞 18 brand-new animated sex scenes (36 new videos), 3 for each breeder:
    • Affection 50: an intimate blowjob scene, with a finish
    • Affection 100: a full sex scene, with a finish
    • Affection 100 (pregnant): a different version of the full sex scene if she’s carrying your child
  • Every scene comes with its own flirty dialogue, written for each breeder’s personality.
  • At key milestones you choose how it ends with the FINISH button.
  • Bond levels give permanent bonuses:
    • +1 population per birth at 50 affection
    • 30% chance of twins at 100 affection
  • A new “Bond Deepened” reward screen appears every time you reach a milestone.
  • Two new leisure facilities that raise colony happiness.
  • Both rooms have their own animated backgrounds.
  • Replay every scene you’ve unlocked: breeding, bond scenes, finishes and more.
  • Open it from the main menu or the pause menu.
  • Your unlocks are kept across all saves.

The whole interface has a new sci-fi HUD look, with new fonts, icons and animations.

  • Colony screen: new top resource bar, side navigation, colony log and a happiness/upkeep panel. Rooms are now cards that show their live status.
  • Breeders: redesigned chamber, profile and recruitment dossier screens.
  • Galaxy map: glowing systems, faction territory lines, ship trails and clearer labels.
  • Diplomacy, factions and intel reports: fully restyled and easier to read.
  • Other screens: research, trades, market, outposts, invasion, colonization and alerts are all redone.
  • Dialogue: a new dialogue box with color-coded name plates for each character, and animated choice menus.
  • Main menu: new layout with big START and CONTINUE buttons and new social links.
  • Menus: new pause, settings and cheat menus.
  • Save/Load: slots now show your colony stats (day, population, credits and more). The menu closes automatically after you load.
  • News pop-ups and video controls have been restyled too.

Combat works the same as before, but it’s a lot more fun to watch:

  • Floating damage numbers and critical hits
  • Hit sparks, bullet tracers and death bursts
  • Screen shake on big hits
  • Kill feed, and battle phase banners
  • Units animate in and out, cast shadows, and leave bodies on the field
  • Animated HP bars
  • A danger vignette, and ambient spores drifting over the battlefield
  • The result screen now waits for the action to finish
  • Floating numbers when you collect resources
  • Rooms pulse when they’re ready, and flash when construction finishes
  • Toast notifications for important events
  • Smooth open and close animations on every window
  • Colonization: the escort now defaults to your carrier’s capacity, and you get a warning if you have no carrier.
  • MAX buttons when dispatching troops.
  • Auto-breed: plays a fallback video when no specific video exists.
  • Cheat menu: new affection cheats (raise or reset).
  • Supporter exclusives: premium breeders now show a proper “Exclusive” screen instead of being hidden.
  • Fixed clicks going through open windows to the colony behind them.
  • Time now pauses properly during combat. This also stops sudden resource jumps after long pauses.
  • Fixed the pregnancy stage display. Breeders now reach the full-term stage correctly on the last day.
  • Fixed auto-breed videos not being found.
  • Fixed misaligned columns in the diplomacy table.
  • Fixed a save error.
  • Fixed character sprite size in bond scenes.
  • Fixed several text display crashes in menus.
