Epic Games has announced it will raise the price of its in-game currency for Fortnite. The company said the increase is needed because the cost of running the game has “gone up a lot”.

The change affects the price of V-Bucks, which players use to buy digital items such as outfits and other content. Epic Games did not give further details about the new pricing in its statement. The company said the decision was linked to higher operating costs.

Fortnite is one of the most popular online games in the world. It is free to play, but players can spend money on optional in-game items. The price rise comes as companies across the gaming industry face higher costs in areas such as development and infrastructure.
