The base is the main center of your operations as we shared in a previous Steam post showcasing the Fossorian base. But how do you control it? Let’s have a look at the UI and all the useful features.


When you enter the base, you can see all the constructed buildings. You can simply click on any structure to use it or access its most common functions via a small shortcut panel. Get new units in the Recruitment Center, hire new commanders in the Fossorian Tavern or trade resources at the Trading Center. All units which are defending the base are visible in the garrison panel. Also notice the right panel with detailed information about income, unit growth, list of all bases, location of the base on the minimap, current day cycle and also a row of quick access buttons which give you another quick way to access the different functions.


The Structures panel shows all buildings which have been or can be constructed at the base. There are several categories of buildings from the economically focused ones like the Tax Bureau and Replicator to the seven upgradeable recruitment buildings like Ratling Slum or the Hammerite Tower.

When your base is strong enough, you’ll of course want to protect it and the structures attached to your Fossorian Stronghold like Defensive Tower or a floating Minefield are the best for that.

And if you want to teach your commanders new abilities, make sure to construct and upgrade the Academy. As you can see on the screenshots, if there are dependencies between different buildings, we highlight them with a slight glow so it’s clear which buildings you need for your next upgrade.


If you have enough resources, you can build a new building once per turn. Many buildings can be upgraded to unlock new functions or the second tier of the unit they produce. If you lack resources, make sure to use the Trading Post, where you can exchange your surplus resources for what you actually need. Unfortunately, the prices are quite unfavorable for you and only get better when you have more bases and more Trading Posts.


Each cycle every base and its buildings produce a limited number of units for hire. You can have a look at your new units in the Recruitment Center. The interface gives you detailed info about every unit in the base, its statistics and capabilities like which units have a ranged attack.


You can also read a bit about their role in the lore. If you are in a hurry, there are shortcut buttons available for all the most common hiring actions.


When you recruit units, you of course also need a commander to lead them. Although individual units can defend the base by themselves, they cannot leave it without a commander. If there are two commanders in the base, you can also activate their meeting panel. That will allow you to not only exchange units, but also equipment or consumables, helping you to manage the strength of specific armies. This panel is still deeply work in progress, but the functionality will remain the same.

Capturing and upgrading your bases is crucial for your economy, but it must always be balanced with other elements to ensure victory. Never underestimate the need to explore. Good usage of all advantages the map gives you can be just as important, but that is something we will show you more about in the future.

How do you like the UI and features we have shown you so far?

The power of your army is not only in the numbers, what is just as important are the actions available to your units. In Silence of the Siren, every unit can be upgraded to a stronger and more capable version. All you need is the second tier of their recruitment building at your base. Of course, upgrading will increase the unit’s stats and give them a cooler look, but it doesn’t end with that, it always unlocks more options. These can be passive skills that give the unit some advantage which works automatically. Or, what is even more fun: special attacks. There are a lot of variations from powerful area attacks to triggering actions which will change the unit’s behavior.

To demonstrate this, let’s have a look at several units from the Fossorian faction as examples.


Ratling Goon is the weakest unit of the Fossorians. His pathetic equipment matches the command's trust in his fighting abilities. Normally all he can do is to hit one unit with his hoe in close combat. But if we upgrade him to Ratling Gunner, he is changed into a ranged unit.


This huge guy is a Hammerite, tier 3 unit. Only one of ten adepts will survive the extensive cybernetic augmentation required to operate a Hammerite power armor. Thanks to the armor, the unit hits so hard that it can strike three units standing next to each other. If you upgrade it into a Hammerite Honor Guard, it will get a mighty weapon called the rocket hammer. Now the unit has unlocked a special ability which makes the hits so strong that they will cause a seismic wave hitting all enemies in its way.


Commissar Cadet is one of the fastest units in the game and can cross almost the entire battlefield. In his basic form, he is a close combat cavalry unit, very useful for attacking ranged units. But if you upgrade him, he will turn into Seasoned Commissar. Once in a few turns he can throw his new javelin, causing an explosion that can hit multiple units in a small area.

Upgrading your units can change the entire gameplay and using them properly gives tremendous advantage on the battlefield. We plan to introduce more units and their special abilities in the future.

How do you like this game mechanic?

Every faction needs its center of operations and that is what we are here to share with you today. As an example, we will be taking a closer look at the Fossorian outpost to demonstrate the mechanics of base building.

And who are the Fossorians, you may ask? Other factions call them ‘moles’ for their similarity to little furry animals from the Earth - it is true that some ancestors in Fossorian evolution probably occupied a similar niche. Still, be careful not to use this name in their presence, you really do not want any of those furry bastards for an enemy.

Centuries prior to the space age, the Fossorians escaped from the polluted wasteland of the planetary surface to the colder but much safer embrace of underground cities. They also brought this architectural tradition to the Siren System as it provides additional protection against bombardment, infiltration, and also citizen emigration. The brutalist style mirrors the overgrown ego of its creators and complements the need for living in the safety of a bunker.



They’re capable of building huge underground structures which can host thousands of warriors and war machines. At the beginning there are only the essentials: a base core to control all operations from, basic fortifications and of course a space bar where bored commanders are looking for a next job.



After a few planetary cycles the base has grown quite a bit. The core building has been expanded and provides more income each turn. It is possible to recruit many more units and they have access to a trading hub so if they lack some resources, they can easily buy them or sell them if they are overstocked. At this stage the Academy has come online and can teach commanders new abilities that can provide a huge advantage in battle.



The Base is now fully upgraded. It is possible to recruit the strongest units in their second upgraded form and teach commanders some of the most powerful special abilities. Other important upgrades increase visibility range around the base, allow heroes to travel from base to base and the fully developed defenses help to defeat even much stronger opponents.



Of course base is just a small part of everything that is needed to conquer the Siren system. There are many structures on the map which provide important resources or even units you can use. But never underestimate the importance of the center of your operations.

We are now working on UI and soon we will show you the different ways how you can interact with your base and with individual buildings. How do you like the design so far?

Hello everyone!

With the year 2022 almost at the end, we would like to take this opportunity to wish you a Merry Holiday and a Happy New Year. We know it was a difficult year for many of you and new challenges didn’t miss our studio as well. But in the end we are excited about what awaits us in 2023.

Even though active development of Project Hospital has ended and no more DLC is planned, we continue to support the game. We added Steam Deck support so you can play the game everywhere. With new patches we tried to improve the game with recent patch 40 being the last one of this year. Our biggest event though was the announcement of Silence of the Siren, a sci-fi turn-based strategy game. For us it is an opportunity to try something new and we hope many of you will join Early Access which we plan to release next year.

The team will now need to recharge a little bit and will be taking a holiday until January 2nd, which means we might not be available on our social channels. If you encounter any issues, don’t hesitate to ask our amazing community on the Steam forum, if they can’t help, we should be able to get back to you at the beginning of January.

We hope the start of your Holiday will be more enjoyable with the Steam Winter Sale where Project Hospital will be available with a 50% discount and 20% discount for all DLCs.

Merry Holiday and Happy New Year!
