Thrive is a free, open-source game currently being developed by an online volunteer team called Revolutionary Games. Drawing inspiration from numerous simulation and strategy games (in particular the original concept behind the PC game Spore), Thrive is a game about a species’ evolution from unicellular organisms to galaxy-wide space travel.

Our team seeks to accomplish two major goals: create engaging, compelling gameplay that respects our players’ intelligence, and remain as accurate as possible in our depiction of known scientific theory without compromising the former. The eventual game will contain powerful creation tools, allowing players to realistically craft organisms, technology, cultures, and even entire planets.

Write Your Own Saga of Life

Thrive’s goal is to encapsulate the player in the wonders of the universe, and to allow them to manipulate the virtual world around them in any way they please by using editors to modify technology, culture, organisms, and entire solar systems. Seven stages are planned – Microbe, Multicellular, Aware, Awakening, Society, Industrial and Space – though for the moment we’re only focusing on the first of these, as the whole project is a massive undertaking.

Simulate, Create

Explore the possibilities of simulation within a game context, competing against the game environment as you wield the forces of evolution. Create and edit an organism on its journey from insignificance to the stars, using all the creation tools at your disposal to rise above your adversaries, themselves products of evolution by natural selection as the game simulates its own ecosystem. Hunt or cooperate with a procedurally generated assortment of organisms as they collect and process resources in multiple biomes.

Difficulty levels can be set by modifying the rate of simulation in the world around you. Quicker evolution rates will pose a challenge as organisms can react to changes in less time, while slower rates won’t put you under as much pressure, so your imagination can run wild as you edit your own species’ anatomy. Choose your own way of playing.

Evolution is gradual, with minor changes made each generation for both you and other species. By collecting substances from the environment and processing them in a simulated metabolism, you can increase your species’ fitness rating, building resistance against extinction. Less successful evolutionary paths will die out, and only one may progress through the crucial transformative steps towards cell cohesion, terrestrial conquest, sentience, settlements and space travel. Will you thrive?

Rise to Galactic Dominance

From the lowly tidepools of your home planet, you will rise to cosmic prominence. Along the way, use behaviour, nation and technology editors, plus many more, to create a culture of your own. Design a roster of units and buildings using Function Parts to conquer the planet.

Defeat the armies of clashing nations within your own species, then travel off-world to do battle with the galaxy’s best adapted organisms. Control a fleet of starships of your own design, defending your own system and colonizing others. Build massive orbital structures, including the Ascension Gate. With it you can rise to a new plane of existence, even bending planets to your will. From your new perspective as the survivor of all life’s trials, watch over your domain, or go back and start all over again.

Join the Community

Along the way, trade save files and creations with friends, challenging them to survive better than you did in the same circumstances. Create brilliant technologies, or simply touch up an organism that could be a little more beautiful.

The game is completely free and open-source, so anyone can join our team provided they have the necessary skills. Visit our Get Involved page to see how you could help. Maybe you’re a talented artist or musician, a programmer, or even an expert in one of the various scientific fields we aim to simulate. We’re always on the lookout for potential new contributors.

Finally, the awaited end-of-summer release is here! It's a couple months after the beta that was released back in March, but we managed to squish in a bunch of new features since then and fix 12 game breaking bugs, some of which were here since pre-0.2.3. That means you should have very smooth gameplay with relatively few crashes compared to the old versions. But don't forget to save often (I spent over a week fixing that functionality)!

In this release:

  • Compound Clouds! Enjoy the fluid compounds as they drift through the currents instead of the ancient, discrete particle emitters
  • Continued Linux Support—Ubuntu, Arch, and Fedora should all work
  • Colored Organelles—organelle materials are now tinted to be the same color as the membranes
  • Damage Indicator—the membrane and all organelles now flash red when you take damage
  • Process System—no longer spend hours trying to get 5 reproductase to reproduce only to have your cell get rid of it once vacuole storage are full!
  • Engulfment Indicator—the membrane flashes blue when you engulf another cell (or another cell engulfs you)
  • New biomes—whenever you die, you will be randomly placed into one of 5 new biomes. Discover them all!
  • Endosymbiosis—engulf free-floating chloroplasts and toxin vacuoles repeatedly until you manage to assimilate them and use them for yourself
  • Gameplay Tuning—less MP in the editor, better steering, less ATP consumed, and others...
  • A bunch of bug fixes—most importantly, the save/load button actually works this time, and won't crash the game on you!


  • Point mouse to turn
  • WASD to move around
  • Mouse scroll wheel (or +/- keys) to zoom
  • E to release toxins (if you have any)
  • G to engulf other cells (you must be bigger in size)
  • ESC to bring up menu.
  • F2 to switch between microbe stage and microbe editor
  • F4 to save your current gamestate
  • F10 to load your previous saved gamestate
  • F12 to save a name-change
  • Symmetry button between undo and redo in editor


Click here to read a more in-depth devblog about this release. It talks about everything we've been working on, as well as other unrelated stuff.


This time, we have both a release trailer and a play through video. The former shows off the various new features, while the later goes into an in-depth discussion of how to play the game.

Have fun Thriving!

So... this is death? Or is evolving?

They released a update a month or two ago on their website. So don't worry, it lives.
