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?

“We started to develop Hide & Hold Out more than two years ago.
We left our jobs & studies to work full time on this ambitious project and managed to create something that is getting close to the idea we had at the beginning, by our own means, trying to not spend too much.
But we knew from the beginning that the project was too big to be entirely completed in only two years by a reduced team.

We have made huge sacrifices, both social and financial, to achieve this progression in the development. We have done all we were able to do by ourselves and that was hard, despite all of our determination, and the fact that we definitely love our job.

Anyway, even without considering our personal situation, we think that everybody knows that developing a game has a cost. Our will to succeed compensates us, and has for a long time, but we think that H2o deserves to have the means to grow with a larger team and the proper equipment going forward into the future.”

Approximately how long will this game be in Early Access?

“To be honest, this question is directly related to our means (especially humans).
If we are able to hire a full team in the near future: the development will progress faster and further, since we plan to bring this project as far as we possibly can.

We are doing our best to complete most of the important features before 2017. But as you can imagine if we focus only that, we will have the entire supporting structure but not the bodywork, the polished paint and the heated seats. If we can put it that way.
That's why we guess that it will be more like searching for a balance between new contents and new features.

We must emphasize that the end of the "early access" does NOT mean the end of the development, in any way!”

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

“We would say that once the game will have reached a fun and balanced gameplay and a suitable stability, there will be no more need to use the term "early access", but, as we already said, it doesn't mean that the development will stop there at all.”

What is the current state of the Early Access version?

“We currently have a version of the game playable enough for it to be submitted to the public.
Even if many elements are still missing. We will pursue the development by considering every want of the community one after one, adding new gameplay where it is the most missing, balancing, testing, polishing...
Always in order to improve the whole game in the best way.”

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

“The price of the game will not change during the early access, but only a little once it is fully released.”

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

“We have tons of ideas for H2o, and some of these promise to be definitely amazing in action. We keep the best ones to ourselves for now of course, but you can find, upvote, submit ideas on Trello. You can also discuss with other players and the developers about the future of H2o on Reddit.

Trello: https://trello.com/b/kDBzUl9h/hide-hold-out-h2o-dev
Reddit: https://www.reddit.com/r/playH2o/

We think that being close to the community is mandatory to make a game that most of the players can love, and having the possibility to see day after day what it is that the community wants the most helps us on that way. This has such a great importance to the development.
A kind of mutual benefit between the player who wants to have fun and the developer who wants to do the things well.”

Development slowed down...

Hello guys, I come to you today with no good news, I'm afraid...

As I said in some previous announcements, I wished to continu the development of H2o as long as I had the money to do it, and I am sorry to say that this day has came... I have no longer the means to ensure a full time work on the game.

I have been forced to shut down some servers recently but I did what I could to keep the softwares that let me develop the game.

This is most likely my fault because I could have acted earlier, when the game was about to be released, I could have contacted a game publisher to be sure to have all that I needed to have a team to work with me as it should be, but I was sure at this time that I was able to do it myself without having somebody above me, who could have forced me to do things I don't wanted. But today I think that I was wrong and that's a shame...

Well, that's a bad news but I don't want to end the development of H2o like this, this is a bad time but everything is not over yet.
Some friends of mine and I will continu to work on the game when we have the time, and maybe someday I will have the opportunity to either make a big update and make H2o take off again, or maybe I will be able to make a true remake of H2o, maybe with another engine, with more experience and wisdom.

But I cannot hide this fact to you, I really tried my best as long as I could.
Today I don't recommand to anybody to buy the game til this situation has improved.

I'm being clear with you all because you deserve it, my dream almost came true thanks to you and I owe you all for this.

And again, I am deeply sorry...

To be continued.

Update - v0.10.10 Live! Battle Mode

Here is the list of the notable modifications that come with the version 0.10.10!

  • The ships now stop by themselves if there is nobody on board.
  • The rotation speed of the turrets (mouse sensitivity) is now centralized for all the turrets and is linked to the mouse sensitivity setting in the option menu.
  • The mouse sensitivity of the turrets is reduced when the player is aiming. To enhance the precision.
  • The turrets with a delayed aim have now two aiming sights: the common one (the dot in the middle of the screen) and a new one that indicates where the cannon of the turret is currently aiming. (which tends to follow the middle of the screen of course)
  • The use of a first aid kit takes time before it heals the player. Moving, switching of tool, taking damage and some other actions interrupt the process.
  • The player is aligned with the vehicle he leaves it.
  • The resolution of the shadows has been improved (no performance cost).
  • The bridge of the Gunboat Erebos has bullet proof windows, to protect the driver from snipers. The driver is still vulnerable if the attack comes from behind.
  • The game shows a proper error screen if the game is started when Steam isn't running at the same time.
  • A new command line / server config has been added: "game_mode=[1-2]". It allows the server owner to decide if the server will start in survival mode (1) or in battle mode (2).
  • A new command line / server config has been added: "score_to_win=[1000-100000]". It allows the server owner to decide of the score that a team must reach to win a game in battle mode. As a reference, a value of 5000 should lead to a game not longer than an hour.

  • FIXED: Fixed a huge performance issue related to the particle system in the client. (more details on trello)
  • FIXED: Reduce or remove the spikes caused by the culling system of the vehicles and ships.
  • FIXED: An item duplication exploit has been fixed.
  • FIXED: if the player dies in a vehicle when you can't leave it, the player will still be using the vehicle after his respawn and he will be able to rotate the vehicle, and so, rotate his character around the map (arount the position of the vehicle) but will still not be able to leave the vehicle if it is totally stuck.
  • FIXED: The building preview wasn't always colliding with the right element, for example: when trying to place a raft on the water, if there was the sea floor one or two meters below the sea level, the preview of the raft was appearing on the sand, and ignored the water plan.
  • FIXED: The console was having an error when trying to use the history when no command had been written yet.

  • BALANCE: The raft is easier to craft.
  • BALANCE: The metal spots give more iron and less aluminum.
  • BALANCE: The speed of the raft has been slightly increased in order to be faster than a player swimming with diving fins.

  • Interact with objects from a ship at "high" speed is still hard, the player must aim at the position where the object will be in the next frames according to the ship speed and direction to trigger the interaction. This issue will be fixed in a coming patch.
  • The loading time of the survival mode is longer than before, this will be fixed ASAP.

The servers have to be updated as well!

About This Game

First of all, you should keep in mind that the game is still a work in progress and so that many things are still missing before starting to see the original idea into its entirety.
If you're waiting for instant fun, maybe you should consider keeping an eye on the game and wait for a more advanced state before going any further.

In the world of Hide & Hold Out, you are one of the survivors of the cataclysm which happened near the end of the 20th century.
This cataclysm has led to a brutal elevation of the sea level all around the globe. Today, you don't really know if there is still a true "land" somewhere, but you know that this reef saved you after the disaster. Well... not only you, actually, and that's more of the problem.

You will have to find by yourself something to eat, materials and fuel to stay alive, to build yourself a home and to start building boats and weapons.
The other players can be a curse in H2o, but they can also be a blessing as working with other survivors will give you the key to both safety and power.

H2o is still far from its final form, but we really wants to give a specific importance to the interactions between the players. Giving you the means to deploy large ships to fight as a team, merchant boats to trade...
We plan to add a skill tree in the near future, so that each player in a group can choose a specific role. Such as scout, driver, gunner, or even a kind of doctor who could craft specific drugs to cure diseases and poisonings.

We want to develop this part of the game with the community, once that the classical structure of a survival game will be properly set, balanced and stable.


  • Multiplayer
  • Open world
  • Player Constructions
  • Fuel & Electricity
  • Crafting & Resource processing
  • Fishing, Farming, Gathering
  • In-game map
  • VoIP
  • Clan system
  • Vehicles

  • Ships
  • Modular Turrets

  • More wild life, Gathering and advanced farming
  • Ghosting & Random events
  • Skills & Specialisation
  • Diseases & Injuries management
  • Bounty system
  • Battle Mode (coming as a free update at the end of the early access)
  • And many others... (Check Trello!)
