Megaquarium Workshop beta goes live!

Hey all, the Megaquarium Workshop has now entered public beta. This means it is open for everyone to use but is currently operating via an opt-in mechanism.

Me want fish! How do I join?
To join the beta you need to join this community group: https://steamcommunity.com/groups/megaquariumworkshopbeta

And follow the instructions from there.

Look at all the exciting things that are already available for you to download:

Why beta?
Firstly it will give modders a chance to get used to the workshop and upload their creations before the full public launch. By the time the public launch comes it should be nicely stocked with all manner of things to play with!

Secondly it gives everyone, modders and players alike, a chance to give feedback on features, request new ones and report bugs.

With that in mind, please take extra care using mods during the beta period. I recommend that you manually save any existing games before applying mods in case they break the game.

Another note: the new mod manager in-game is in English only currently. When the full launch comes it will be localised into your local language.

How long will the beta last?
This depends on the volume of feedback/requests that come back. Somewhere between 2 and 6 weeks is probable.

Dev blog - 7th May 2019

Hey guys, just a quick post to let you know the latest with the game.

Dev away for 2 weeks
The first news is I'm going to be away for a couple of weeks from today so I won't be able to answer any questions via the forum or email until I return on 23rd May. Hopefully other players will be able to pitch in and help any new players to the game. :)

Steam Workshop
But don't worry, the next update is already well underway. One feature that has been highly requested ever since launch is Steam Workshop.

I'm happy to announce that the next update will include support for this. I'm about half-way through implementing it and I'm looking to release a beta with the new features soon after I return.

This will give a chance for our enthusiastic modders to populate Steam Workshop with new and interesting mods so that when the official release comes there'll be lots of new things to try out.

As part of this I'll also be releasing a basic modders guide to cover the basics of modding the game. You'd be amazed at the sorts of things you can add with just basic text and image editing skills; things that can have significant gameplay impacts.

I'm really looking forward to seeing what people create.

And after that?
I can also announce that I am in the early stages of working on the next batch of official content for the game.

I can't reveal all the details yet but I thought players would appreciate knowing that something new is in the works.

That's it for now but stay tuned in the coming months for lots more exciting stuff in the world of Megaquarium. :steamhappy:

“A charming watery theme park management game where fish are friends, not food. Until they eat each other or you forget to feed them.”
86 – PC Gamer

“Megaquarium is an fantastic tycoon title with a surprising amount of depth.”
85 – GamingTrend

“As a tycoon game, Megaquarium strikes a very nice balance between having too much complexity vs. not having enough depth to remain entertaining.”
80 – Gaming Nexus

About This Game

From the creator of Big Pharma comes a brand new economic simulation game. Megaquarium follows in the footsteps of classic theme park management tycoon games and adds an aquatic spin!

A living simulation

Starting with just a few tanks and the most basic of livestock, you’ll grow your aquarium to a thronging metropolis filled with hundreds of guests, tens of staff and a multitude of different aquatic lifeforms, each with their own unique care requirements.

Design your exhibits

Megaquarium features almost 100 different marine species including fish, sharks, crustaceans, corals, jellyfish, other invertebrates and even a turtle! You’ll be spoilt for choice as you design, decorate and populate your tanks.

The right staff for the job

You won’t get far without the right staff. Choose who to hire based on their skills and future potential. Will you train up a team of multi-disciplined staff or a set of super-focussed experts? You’ll have to weigh up the pros and cons of each strategy and work out what is right for your aquarium.

Research new animals and technology

As guests experience your displays you’ll earn points which you can assign to discovering new livestock and equipment. Keep upgrading and expanding your aquarium and work your way up to the most prestigious animals and displays in the aquarium industry.

Manage your finances

The latest fish might look cool, but have you considered its impact on your aquarium’s bottom line. Tricky animals may require new staff to be hired, expensive fish food or supplements and the best tanks are a hefty investment! As aquarium curator you’ll need to master creativity and economics to succeed.

Manage your guests!

Keep your guests happy by providing them with seating, food, drinks and toilet facilities. Then at the end of their visit, direct them through the gift shop to boost your profits!

Curator school

Start your career in the campaign mode where you’ll learn everything you need to know about designing and managing an aquarium. Each of the 10 levels challenges you to build an aquarium with unique gameplay conditions and objectives, while new features and concepts are explained along the way.

Dive into the sandbox

Next explore sandbox mode where, with customisable settings and a random challenge generator, you can find virtually unlimited fish-related gameplay!

Easy to learn, difficult to master

Running an inefficient aquarium is easy. To really thrive and take on the greatest challenges you’ll need a lateral thinking brain and attention to detail. Will you group your animals by food type, water quality or something else entirely? Will you locate your equipment in a centralised hub using pumps or spread them out embracing the zoning system? How will you optimise your layout so that visitors can find your tanks and staff can easily access them?

Every decision you make in Megaquarium has consequences. Your choice of animals, filters, tanks, staff and layout all have subtle and far reaching effects on each other. Experiment, adjust, learn, reapply and most importantly, have fun!
