Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Selling DinoSystem in Early Access allows me to invest more time into the development, and get precious feedback from the community while the game is being developed.”

Approximately how long will this game be in Early Access?

“There is no current ETA for the final version, but you can get an idea of the current development stage by checking the game version: for example, v0.70.0 means the game is 70% complete.
I want to continue improving the game even after the Early Access, so as soon as all the core features and content are in place (v1.0), I'll release it as a full product, but the development will continue (at a slower pace).”

How is the full version planned to differ from the Early Access version?

“There are some core game systems missing, like the God Mode tools, game lore, and more content. The game gets more refined with every update, so it's difficult to be specific on how it will differ when completed: it will be better, rest assure of that!
You can assess the progress towards the full version on the development roadmap page.”

What is the current state of the Early Access version?

“The current alpha build offers an already exciting sandbox survival experience, which lacks variety and content (especially craftable items). God Mode (the game mode where you manage the ecosystem) still lacks a proper GUI and tools to interact with the world, but the ecosystem mechanics are in place, and you'll see animals reproduce, seasons pass and vegetation spread.”

Will the game be priced differently during and after Early Access?

“No price change is planned.”

How are you planning on involving the Community in your development process?

“I value all feedback and always check the forum for suggestions and bug reports. I'm adjusting my development plan according to the feedback received, when necessary.”

December 31, 2018

Update v0.85.0 - Character Presets, Controls tweaks, AI expansion, many improvements!

This update IS compatible with savegames from previous v0.80.0+!
But it's still advised to start a new game, as some changes could potentially cause glitches.


--- NOTE: this announcement comes few days late, as the update was released on December 26th ---

"Direction" option renamed to "Control Mode" and expanded:
- "Absolute" renamed to "Keyboard", which controls the character moving direction with the keyboard input (as before), but now it applies ALSO to the character angle. KEYBOARD is now the default option when the game is first started.
- "Relative" renamed to "Mouse", and works the same as before.
- Added a new option called "Mixed", which is like "Keyboard", but retains the ability to turn the character with the mouse (same as "Absolute" before this update).
- When triggering a melee attack from the Keyboard, the character will automatically turn towards a close-range frontal target (check the survival section for more info about it).
- Removed the possibility to bind a key for changing the Control Mode (default was T), as it was unnecessary and could be pressed by mistake, confusing new players.

Added "Preset" character builds in the Character Creation Screen:
- Presets are pre-defined starting character builds.
- Presets are a good starting point to build your character pursuing a specific playstyle.
- There are five presets: Default, Survivor, Hunter, Runner and Tanker, each with its pros and cons, and more will probably be added in future updates.

Added Player melee assist and attack action improved:
- When triggering a melee attack from the Keyboard, the character will automatically turn towards a close-range frontal target (animal or tree) before performing the attack. If attacking from LMB (left mouse) or in Ranged, the attack direction is still fully mouse controlled.
- When hitting a target (melee) or when firing a projectile (ranged), the character cannot turn for the duration of the attack delay (red attack bar), preventing him/her from exploiting the turning mechanics and limit/avoid stumbling.
- Attack precision and collision detection vastly improved.
- Wind impact on projectile trajectory reduced and rebalanced to have a minimum wind power threshold.
- It is now possible to hit trees with all weapons (even with the punch!) dealing a small damage to the trunk and potentially chopping down small trees, but doing that without a cutting weapon triggers a hint suggesting to use an Axe/Sharpstone instead.

Animal ecology rebalanced:
- Animal energy/water/stamina expenses rebalanced.
- Number of eggs layed per species rebalanced, and it no longer scales with species population.
- Fighting/hunting events outcome rebalanced and made minor tweaks.
- Energy/water gained from food rebalanced, and eating action improved.
- Triceratops and Ankylosaurs feeding preferenced tweaked to let them occupy slightly differenct ecological niches.
- Improved how the game evaluates how well every species is doing, taking into account more parameters.
- Removed some artificial balance enforcing mechanics, as they're no longer necessary.
- Tweaks to the animals aging system.
- Some rebalancing to animals generation at game start.

Animal AI improved and expanded:
- Predators are now much better at evaluating which animals they should hunt, taking into account more parameters and with less restrictions (previously, they only hunter members of the more numerous species).
- T-Rex can now grip and carry away a small carcass, if they see another T-Rex nearby, in order to feast on it alone.
- Male Troodon will now stay close to his partner after mating, and help her protect the nest.
- Improved how mothers guard their nest.

Added Alpha specimen system:
- Triceratops and Troodons now have Alpha male/female, which can lead the pack and take some decisions.
- The Alpha specimen is usually the strongest and/or oldest member of the pack.
- Triceratops have harsh confrontations to decide who'll become the Alpha male.
- The Alpha male/female has slightly more vivid colors.

Added Animal hibernation system:
- Animals hibernate in three occasions: when they cannot find/water food and are starving/dehydrated, when their species is close to extinction and they can't find a fertile mate, and during a particularly cold winter (only Troodons).
- While hibernating, the ZZZ sleeping icon is red.
- While hibernating, Stamina is always 0 and the metabolic functions are slowed down to 1/5, allowing the animal to endure starvation, hydration or lack of fertile mates.
- While hibernating, the animal can still be awakened by attacks or other events (receiving a Stamina boost).
- If starving/dehydrated during hibernation, the animal has a chance to wake up for some time (receiving a Stamina boost), in order to find what it needs.

Added animal action pop-up text:
- When performing certain actions, animals now show a pop-up text next to their head with the action name.
- The actions shows are: fleeing, eating/drinking, falling asleep, waking up, mating, laying eggs, winning/losing a fight, and few others.
- In Survival mode, the action text is shows with a chance equal to the character Zoology skill.
- In God mode, the action text is always shown.

Other addition and fixes worth mentioning:
- [Survival] Added dynamic mist effect, which is only visible in Survival mode, but depends on actual weather variables.

- Clouds effect improved and made more vivid overall (plus more weather visual improvements).
- Major optimizations to clouds, cloud reflections and cloud shadows logic.
- Asteroid chance decreased by 15% for "Likely", and by 100% for "Unlikely" (which is now REALLY unlikely!).
- [Survival] Items are now highlighted when the mouse is over them.
- [Survival] Skills at -100% progress now have a chance to decay when the player is exhausted (low Stamina) and when receiving damage (chance based), instead of just instantly decaying when passing out (at 0 Stamina).
- [Survival] When performing actions like gathering, drinking and eating while having both hands holding item/s, the character will drop them from the right hand ONLY for the duration of the action and take them back as soon as the action is finished, instead of keeping them on the ground, which forced the player to manually retake them.
- Various improvements to the movement system and pathfinding, making animals turn more smoothly and follow their mother/partner/peer more efficiently.
- [Survival] Fixed (finally!!) the infamous "permanent auto-walking while drinking" bug (also fixes corrupted saves).
- Fixed animals sometimes repeatedly bumping into an obstacle (wall, boulder) while trying to reach a target (like food or prey) which is on the other side of the obstacle.

These are only the most relevant changes, as always there are tons of other in this update, check the full changelog for the complete list!

About This Game

DinoSystem is a 2D, top-down ecosystem and survival simulation that allows players to either manage the ecology of an evolving island (inhabited by dinosaurs), or survive in it as a human, dealing with realistic survival mechanics, and with a deep character progression system that tracks how your character's body adapts over time.

An emergent, living world:

Everything on the island is subject to biological and physical rules, and nothing comes from nothing: will you hunt the last dinosaur of its species for a steak, or will you protect it from extinction and make sure its eggs hatch? These are the dilemmas you'll face in the game, as long as YOU don't get extinct.


To see all the features planned for the full release and the ideas we are considering, please check the development roadmap, and feel free to join the discussion and make suggestions!

Game Modes:

  • God: Manage the island ecology, change the weather, trigger devastating events, and see how the ecosystem adapts.
  • Survival: Join the island as a stranded human, see how long you can survive as part of it, and how your body changes in the process; the game offers the option to play either with "casual" or "hardcore" difficulty.

World Features:

  • Ecology simulation: the game simulates a Cretaceous ecosystem populated mainly by dinosaurs, animals and plants don't "spawn"; they are born, then grow, reproduce and die.
  • DinoSystem uses a complex seasonal model that calculates day/night length, relative position of the sun, and influences the weather. Seasons transition is gradual, no sudden change between two seasons.
  • Realistic weather model that takes into account variables like time of day, humidity, temperature, and pressure; generating weather conditions like rain, snow, wind, sand/snowstorms, thunderstorm and fog.
  • Thunders can trigger huge wildfires, burning down entire forests.
  • Realistic water cycle: rain creates puddles that can either evaporate or grow into ponds and lakes. Evaporation takes into account air humidity, temperature and sun exposure.
  • Terrain changes according to factors like presence of water, weather, vegetation, and location. Any area can become fertile or arid, new forest or grasslands may form or disappear over time.
  • Fire (from torches to campfires and wildfires) consumes available fuel, releasing heat and light, and it's influenced by air humidity and wind; you body and all objects near a fire are heated up. Fire can spread to nearby vegetation and trigger a wildfire, if ambient conditions are favourable.
  • Animals AI allows them to survive in their world and adapt; they'll reproduce, care for their youngs, look for protection or compete for food and mating.
  • Each new island is randomized at game start, based on parameters set by the player.
  • Everything, from dead animals to branches, decomposes based on factors like temperature, humidity, and location. There is no "timer" after which an item or a carcass disappears.

Survival Features:

  • Deep, complex and rewarding character progression system: metabolism, body muscles and fat change according to your lifestyle, and even your character's sprite changes in appearance to reflect this. Get fat to survive winter, get slim to be lighter and swifter, or get muscular to be stronger in combat and more capable of hard work, but make sure to eat enough proteins...
  • Needs like thirst and hunger are not just bars that drop at a constant rate: everything, from performing actions to metabolism and body weight, influence the rate at which you burn calories, consume water or get tired. For example, high temperature or intense activity make you sweat, requiring you to drink more water.
  • Dozens of skills, both mental and physical, that raise as you perform a particular action; but can also decay if you don't use them for a long time (only in "hard" difficulty!).
  • Crafting system allowing you to create items and weapons, advancing in technology at each step. NOTE: few items are craftable in the current Early Access build; expect many more to be added throughout the development!
  • Foods with different nutrition values: meat is valuable because of proteins, but make sure you cook it...

Many more features will be added throughout the development! Again, check the development roadmap, and feel free to get involved and suggest new features.
