About this game
ROTTING WORLD
The story of MOULD unfolds in an alternative industrial version of the Soviet Union at the end of the 1940s. There was no World War II; construction sites are bustling across the USSR, and scientists are diligently working on creating steel builders for a bright future. At one of the mining enterprises, miners come across something unimaginable, and humanity faces a deadly threat. From the depths emerges a parasite — a creature capable of controlling living organisms, gradually devouring them from within. As it reproduces, it begins to alter the environment, making it more comfortable for itself but unbearable for the planet’s ordinary inhabitants.
HIDE OR DIE
The creatures of the parasite know that you are alive. He needs to find you and destroy you. The best option is to remain invisible to the entire ecosystem, act stealthily, and attack with lightning speed. Otherwise, you will have to face creatures that are stronger than you. They will do anything to tear you apart, as the parasite wills.
A small arsenal of melee and heavy firearms will help you to effectively destroy the infection. You will also have at your disposal a family of experimental shotguns filled with poisonous ammunition. But you shouldn't relax, every cartridge here is worth its weight in gold.
DIVE INTO SMOLDERING RUINS
A huge region, divided into areas, awaits you. In each of them, you will have to explore the territory while simultaneously destroying the infestation.
To unravel the mysteries of what is happening, look for workers' notes and carefully examine your surroundings. Who knows what the parasite has carefully hidden from you.
GAME FEATURES
The environment captures the atmosphere of a dying, once-prosperous world.
Large locations that can be explored in different ways.
A variety of weapons: from a knife to a chemical spray gun.
Dynamic difficulty in the form of a progressive disease affecting the player condition.

Development News #1
Hello everyone, it's finally time to wake up and show what's in development right now. After the playtest, I received a lot of good feedback, all the problems are on the way to being solved, some things have been redesigned or completely removed, and you will learn about all the changes in future news.A MINIMAP AND A SEARCH FOR KEY ITEMSOne of the key problems in the techno demo, which I immediately began to solve, is a lack of understanding of where you need to move and what the game wants you to do. To solve this problem, I added a full-fledged three-dimensional mini-map of locations. What is displayed on the mini-map is related specifically to the area in which the character is currently located. For example, let's take the "Drain" area as a basis: all the boxes, storage and blood collection stations (which have also been redesigned), as well as the mini 3D version of this area itself, will be displayed in the minimap window, but the other two areas, as well as their boxes and stations, will not be displayed until until a character enters their area of action. As soon as he does this, the content of another area will be displayed, where the character has entered. This is done in order to display a specific area without overloading it with unnecessary sections.In the future, I will talk about markers, they have also become a mandatory part of indicating the path, but they can be turned off if they get in the way, I focus on both hardcore and comfort.ACID PIPESThe new and key mechanics of the game are acid pipes. The principle of operation is simple: for acid, it is necessary to pave the way through the pipeline from point A to point B by moving the valves. The mechanics will be used to destroy the "rot" growths that prevent further progress.APPROVAL OF WEAPONS AND ENEMIES, LOCATIONS AND MECHANICSAt one point, I realized: STOP. I put together a whole hodgepodge of different mechanics, and in order not to drive the game into production hell by pointlessly adding, re...Read full article on Community Announcements (Kroll)Patch NotesOfficial
