Hi everyone,

I am thrilled to introduce my very first game, Symbiosis Primordial, a 100% free project that I developed entirely solo.

The concept was born from a deep sense of nostalgia after replaying Spore. I wanted to capture the fascinating essence of its first phase (the primordial soup) and bring it up to date, but with a deep RPG and Rogue-lite dimension to make the experience endless.

The game has just moved into Version 1.8, a major update that completely redefines the gameplay.

🧬 Here is what awaits you in the abyss:

• 🌊 Hydrodynamics & Newtonian Fluids (New in 1.8): Immersion gets physical. Fluid dynamics now dictate all movements. Cells and their prey interact with inertia, liquid drag, and water viscosity for a dense, organic, and ultra-"juicy" gameplay feel.
• 🌍 20 Unique Biomes & Infinite Abyss: Explore 20 distinct environments, each with its own ecosystem. The final biome shifts into an endless, procedurally generated gulf that scales dynamically with your level.
• 🧪 Real-Time Genomic Fusion: Over 40 active and passive skills. Don't just mindlessly collect genes: fuse your organelles on the fly to engineer unique hybrids and break the food chain.
• 👾 40 Symbiotic Pets: Tame unique micro-organisms that orbit your membrane to automate your defenses, buff your stats, or scavenge nutrients for you.
• ⚔️ A Colossal Bestiary: Face off against more than 80 enemy archetypes and challenge 20 unique, terrifying bosses slumbering deep within the Bio-Void.
• 🤝 Sync (PeerJS) & Asynchronous Co-op: Purge the depths with a friend in real-time with zero registration required, or import a friend's genetic code to have an AI-controlled version of their cell fight by your side.
• 💾 Lab Save System: A transparent save method using JSON codes to easily export and import your precious mutations from one session to another.

Transparency Note: Since this is my very first game development project as a solo creator, I use AI tools as assistants to help me code, optimize, and bring this massive vision to life.

The game is fully optimized for PC, Browsers, Android & iOS. I am highly eager to hear your constructive feedback, build ideas, or balance suggestions. Thank you for your support!

🔬 Symbiosis Primordial

Evolution is not a choice. It is your only weapon.

🌍 Languages: 🇬🇧 English | 🇫🇷 Français

The abyssal ecosystem knows no mercy. In this dark, ultra-hostile organic wasteland, the law of the deep is absolute: hunt, absorb, mutate... or dissolve into nothingness.

In Symbiosis Primordial, you take control of an unstable cellular entity cast into a fascinating yet brutal primordial soup. Track down your prey, tear apart their genetic code, and graft real-time mutations onto your membrane to withstand the terrifying monstrosities lurking in the void.

🧬 NEW EVOLUTION STEP

🔬 VERSION 2.1 PATCH NOTES

The Ultimate Resonance Update

A new frequency has been detected deep within the cellular void. Harness devastating power with catastrophic new active abilities, monitored through a completely overhauled, crystal-clear bio-interface.

💥 Ultimate Resonance Sequences Unlocked!

Discover 10 new unlockable unique skills capable of warping the laws of the deep abyss. Because of their sheer catastrophic power, these skills cannot be automated. They require precise manual activation by the player to trigger cataclysmic cellular chain reactions. Time your resonance perfectly to completely obliterate the food chain!

🖥️ Next-Gen Bio-HUD & Interface Enhanced

❤️ Vital Status Monitoring

Complete visual rework of player vitals. Your health bar and shield indicators have been refined to offer instant, hyper-clear readability even in the heat of chaotic underwater combat.

⚡ Dynamic Action & Skill Bar

The skill bar has been upgraded to seamlessly display cooldowns, ready-states, and activation triggers for your standard mutations and your newly discovered Resonance abilities.

📢 Polished Pop-ups & Displays

In-game notifications, screen text overlays, and vital announcements have been modernized to blend beautifully with the dark, cyber-organic theme of the lab.

⚙️ Balance & Core Optimization

• Performance Boosting: HUD rendering has been optimized to reduce graphic overhead. Combined with further tweaks to the Newtonian physics calculations, the game runs smoother than ever on both PC and mobile web browsers.
• Ecosystem Rebalancing: General stats and enemy scaling curves have been re-calibrated to accommodate the raw power of manual Resonance Sequences, ensuring the endgame remains as challenging as it is rewarding.

Unlock your true cellular potential. Play the updated version right now on your browser! 🧬 Trigger Resonance in V2.1

As always, your feedback is crucial to refine the balance of these devastating new skills. Thank you for your amazing support!

Abyssally yours, Yze.

🚀 QUANTUM EVOLUTION STEP

🔬 VERSION 2.2 PATCH NOTES

The Dynamic Adaptation Update

The abyssal matrix is shifting. Introducing a sentient quest structure that reads your exact cellular power, alongside an explosive expansion of ultimate skills and genetic fusions.

🗺️ Sentient Dynamic Quest System

An endless gameplay cycle has arrived! Version 2.2 introduces a brand-new Dynamic Quest System that automatically analyzes your current level and Gearscore in real-time. It dynamically scales mission parameters to generate infinite personalized challenges and high-tier rewards tailored to your exact strength. No two runs will ever feel the same!

🧬 Genome & Apex Ability Overflow

💥 Ultimate Resonance Sequences: From 10 to 20!

We have doubled down on your catastrophic endgame powers. 10 entirely new Ultimate Resonance Sequences have been added, pushing the arsenal to 20 total ultimate abilities. As always, these hyper-destructive spells require manual activation—no auto-mode can handle this raw cellular power.

🧪 Ultimate Fusions Expanded: From 20 to 24!

Push synthesis to absolute apex dominance. 4 new highly volatile genetic fusions have been uncovered. Combine rare active and passive traits to mutate your cellular structure into devastating biological hybrids.

🖥️ Interface & System Optimization
