It looks like two versions of the game will be available for pre-order on the official Atomic Heart website soon. In addition to the game itself, the store plans to sell additional merchandise, such as T-shirts.
The information became known from the official Discord channel of the game, where screenshots of the store first appeared.
The section is still under development, and the screenshots presented above are only blanks, and by the time of release, the extra elements (size selection) will be removed.
The price of the game is also subject to change.
