Computer entertainment retailer Game is to sell its interactive online package, Game.Net, in its 330 stores.
The online gaming facility allows customers to register and play games live with other people on a Web site.
Game.Net was initially launched in January, but could only be bought through the retailer's Web site. Now, customers can buy it in-store.
Subscription to Game.Net is£25 a year or£9.99 for three-months. The retailer has backed up the in-store launch with offers, such as half price PC games, when shoppers subscribe to the service.
A spokeswoman said: 'The tagline (for Game.Net) is 'multiplayer made easy' and we are targeting a much larger audience than we did before with Barry's World.'
Game acquired online gaming site Barry's World two years ago and has used it as a model to develop Game.Net. Barry's World remains a channel within the Game.Net site.
