Project Exilium – Breeding Protocol is a sci-fi, roguelike deck-builder inspired by Slay the Spire, where strategy and NSFW collides.
You command a party trapped in a hostile alien system where survival depends on mastering unstable elements, strange technology… and a Breeding Protocol that you activate by reaching maximum lust.
Every run is shaped by your choices:
-The elements you select (each character combination gives you access to different cards and playstyles)
-The cards you obtain
-And how deeply you embrace the system’s lewd and dangerous mechanics

🔥 NEW CONTENT
15 new adult scenes across multiple story paths, expanding intimate encounters with the full cast. Every character has new NSFW content to discover.
Louise is here. Our radiation specialist joins the roster as a fully playable hero with her own unique card set, combat identity, and story scenes. She brings volatile damage-over-time strategies and some of the most dangerous card synergies in the game. 🔒 Supporter Exclusive — thank you for making her possible.
5 new enemy types added to the bestiary, each with unique attack patterns, intents, and animations. The colony just got a lot more hostile.
New cinematic intro — a fully produced video sequence that sets the tone before you hit the ground on Theta-9.
⚙️ SYSTEMS & PROGRESSION
Dynamic dungeon generation — every run now builds a randomly generated map with branching paths, encounter variety, and unpredictable routes. No two runs play the same.
4-act campaign structure with escalating difficulty, unique bosses per act, and hub ship sequences between acts for healing and shopping.
Ascension mode unlocks after clearing the campaign. Rise through 5 ascension tiers, each stacking new modifiers: → Ascension 1: Enemies have +15% HP → Ascension 2: Start each act with 1 wound card → Ascension 3: Enemies have +30% HP → Ascension 4: Rest zones heal 25% less → Ascension 5: Enemies have +50% HP. Good luck.
🛠️ FIXES & QUALITY OF LIFE
→ Fixed exceptions that could crash the game when clicking or playing cards during certain states → Fixed character overlap — heroes no longer stack on top of each other during dialogue scenes → Added colored character names in dialogue, making conversations easier to follow at a glance
