Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 24 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Mycosis is a mix of action and puzzle platformer in the style of classic games. It’s been set in dusty corridors of a mysterious research facility that comes alive and kicking, and it’s up to you whether you blast your way through with a flamethrower or find a way to overcome the traps and puzzles using found objects and environmental features.
You know how it is when you come to work in the morning and a strange infection spreads through the ventilation, turning your colleagues into fungal zombies... Classic. The story of the game is inspired by my vocation as a microbiologist (no, The Last of Us wasn’t the inspiration) and contains many references to both current and past aspects of the Institute of Microbiology (MikroBiologický Ústav in Czech) — hence the subtitle Heroes of MBÚ.
Since childhood, I wanted to create my own game. This debut is my humble tribute to the legendary games like Abuse, Half-Life and the original Fallout. I built the game on my own engine, in Java, as an amateur enthusiast which took me over eight years. It was a long - but amazing - journey. It allowed me to dive in and take pleasure in full creative freedom.
Now! I hope you’ll enjoy as much as I enjoyed creating it!

Reviews
Sleva, přidány achievementy. Jako fanda HL mě nalákala, i svou češtinou. Po cca odehrané hodině zažádáno o vrácení peněz s uvedeném důvodu: "Zabugovaná hra. Která se mi kvůli špatnému řešení autosave už nechce hrát od začátku. Jedná se konkrétně o situaci, kdy se mi načte autosave a postava okamžitě umírá. + nezapočítávající se achievementy a stejně jsou špatně řešeny ve smyslu tom, že z nich jde zle poznat, co třeba udělat. Zkrátka hra nesplnila očekávání. Jediné, co snad na ní mohu ocenit, je čeština. A to je sice dost, ale trochu málo pro celistvou hru." A to jsem ještě nezmínil, že mi defender tam zablokoval nějakou potenciální hrozbu. Vůbec to za tu cenu nestojí. Jedno euro je skoro moc pro tu hru. Jako Free to play už by mohla být obstojná.
