Biosys Inc. is a biology simulator that takes you to a new planet where you will be responsible for the process of abiogenesis. Start with a single cell and watch your ecosystem thrive by itself. All cells carry DNA that will allow them to mutate and evolve into complex beings.

A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Next month it should be ready to roll, you'll be able to look inside your cells and upgrade them with... well, cell stuff. Mitochondria, Golgi, Centriole, Chloroplasts, Leukoplasts, Lysosomes, the works. If it's inside a cell, you'll be able to bring it to do whatever it does. But, devs, I don't know anything about biology and I don't know what a centriole does. Well, that's why you're playing Biosys Inc isn't it? It's better than studying for that biol

Hello everyone! We're super excited to share with you the work we've been doing on: - The terrain, now with weather effects (and affections) - The cnidaria (a second species coming soon), a dangerous predator with excellent defense systems - The porifera, an animal we know so little about (usually), very resistant to radiation (and cancer), that will be breaking it's parts in your ocean now (and making everything pretty of course) - Sophie's voice - our beloved AI will not go on voiceless and now (little by little) we're recording our very own Rachel Morin (awesome molecular biologist) who bec

In this Update we will open the world outside for you. Fly around with Emmanuel BT9 to explore it and use the genes you fought for in the cell stage to create fungi (we'll start with basidiomycota and ascomycota), plantae (phytoplankton, magnoliophyta and bryophyta) and animalia (Opabinia Regalis, more coming soon!). In this update: - Go outside and use the genes you made to create fungi, plantae and animalia - Experience the weather and temperature variations and see how they affect the life you created - Go underwater, but be careful - Emmanuel's shields can only take so much pressure don't

ENGINEERED E.COLI 5.9 Hello everyone! Before anything else, I want to thank everyone that has been playing and helping us build the first game by Fire Game Studios. You're all breathtaking! We've been working around the clock to balance our biosystem and try to make everything difficult, but fair. We also have some great news about those brave enough to reach level 4 - Genetic Engineering! Now, you'll be able to spend your hard earned money on genetically engineered cells and choose dominant and recessive genes. You even get a mutation for free (for better or worse, as always). - Genetic engin

Thank you for all that started playing Biosys Inc! All the feeback is giving us a lot to work on and we love it! We checked all the bugs related by players and here's what we fixed in this small update (Sassy Mitochondrion 1.0): FIXED 1) An issue with mitochondria and chloroplasts not breathing oxygen or producing ATP during photosynthesis. 2) Some missions not giving money in level 1. NEW STUFF 1) New icon to represent the random mutation that WILL happen if you press a number that doesn't have a RNA strand in it These things are not in this update, but we're working on them: 1) Some O2 field
