As Electronic Arts prepared to market Medal of Honor Warfighter, the latest version of its top-selling video game released in October, it created a Web site that promoted the manufacturers of the guns, knives and combat-style gear depicted in the game.

Among the video game giant’s marketing partners on the Web site were the McMillan Group, the maker of a high-powered sniper’s rifle, and Magpul, which sells high-capacity magazines and other accessories for assault-style weapons.

Links on the Medal of Honor site allowed visitors to click through on the Web sites of the game’s partners and peruse their catalogs.

“It was almost like a virtual showroom for guns,” said Ryan Smith, who contributes to the Gameological Society, an online gaming magazine. After Mr. Smith and other gaming enthusiasts criticized the site, Electronic Arts disabled the links, saying it had been unaware of them.
