Important Notice: Upcoming Price Adjustment & Steam Summer Sale
Hello Spores,
Following up on my recent announcement about the new Co-Op Update, I want to share an important update on the future pricing of Mycelium Conquest.
To reflect the substantial expansion in gameplay value and replayability that co-op brings, the base price of the game will increase from $9.99 to $14.99 USD on July 10th (regional pricing applies — your local price on the store page may differ).
Last Chance: Save 20% in the Steam Summer Sale!
I want to be upfront with everyone who has wishlisted the game, so you have a fair chance to grab it at the original single-player price point before the change takes effect. Mycelium Conquest will be in the upcoming Steam Summer Sale (June 25 – July 9) at 20% off — the lowest discount it will see at the current price tier before the permanent move to the new co-op pricing.
If you have friends you want to team up with for the new co-op mode, this is the perfect time to grab extra copies before the transition on July 10th.
If you already own Mycelium Conquest: THANK YOU. The entire Co-Op Update is yours, free — it's already in your library.
Thank you all for your incredible support.
Best regards,
YCF
