Free-To-Keep Deadline

Steam users have a narrow window to lock in a full game for zero dollars: the 2021 indie horror title Depths of Horror: Mushroom Day is free to keep if you claim it by April 6. Once you hit the "Add to Account" button on its Steam page while signed in, it’s yours permanently. No download required today, no strings attached.

Normally priced at $4.99, Mushroom Day comes from a small studio and fits the pattern of Steam’s occasional free-to-keep promotions that spotlight lesser-known projects. These drops can be an easy way to build a backlog without spending, especially when paired with the Epic Games Store’s weekly freebies. Checking both storefronts pays off if you like surprises.

What Is Depths of Horror: Mushroom Day?

Made by indie developer TakeThem.Games, Mushroom Day is a single-player horror release from 2021. It’s the studio’s most recent game, following experiments in very different genres like Vaccine Delivery Simulator and Brother!!! Save Him!. The Steam description sets the tone with a simple hook: "While picking mushrooms in a clearing, you stumble upon an abandoned hut. Exploring it, you find yourself in a cave full of unexpected inhabitants and surprises."

On the feature list, the developer promises a "unique system of hand-crafted caves," "frequent events will not make you bored," and a mix of "enemies and screamers." There are eight Steam achievements to unlock, which completionists may blast through quickly. Expect a compact, atmospheric run rather than a sprawling survival horror campaign.

Early Player Response

The free giveaway has triggered a rush of new reviews on Steam, and the verdict so far is mixed. Some players praise the eerie mood and the straightforward path to 100% completion thanks to those eight achievements. Others push back on the short runtime and what one review calls "cheap deaths," suggesting sudden fail states that can frustrate.

One recurring note: spiders. They play a central role, according to multiple user posts, so arachnophobes may want to tread carefully. For everyone else, the barrier to entry doesn’t get lower than free, making this an easy add to your library even if you only sample it later.

How to Claim and What Else Is Free

Claiming the game is quick:

  • Sign in to your Steam account on the store page.
  • Click "Add to Account" for Depths of Horror: Mushroom Day.
  • Walk away—you don’t need to install it now to keep it forever.

The offer ends April 6, after which the game returns to its standard $4.99 price. If you’re hunting for more no-cost picks this week, the Epic Games Store is giving away Havendock, Hyper Echelon, and Together After Dark. Between Steam’s surprise freebies and Epic’s weekly rotation, there’s plenty to claim without opening your wallet.

Short, scrappy horror games can be hit or miss, but free-to-keep drops like this are a low-risk way to find a late-night thrill or pad a backlog for a rainy weekend. Set a reminder before April 6, skim the reviews if you’re on the fence about spiders, and grab it while the button still says free.
