Konami has reported a drop in sales and earnings for the nine months ended December 31, 2012.
Sales generated by the Pro Evolution Soccer and Metal Gear publisher's digital entertainment business fell almost 20 per cent year-on-year to 80.6 billion yen (£550m / $860m).
Meanwhile, operating income declined from 24.3 billion yen (£165m / $260m) the previous year to 15.6 billion yen (£105m / $165m).
The Japanese company said "the latest title in the Winning Eleven (known in the US and Europe as Pro Evolution Soccer) series was released and sold steadily".
The corporation as a whole also posted a drop in revenue and net income during the first three quarters. And citing the delay of new content for social networks, along with the postponement of the release of its main pachinko machines until the next fiscal year, Konami downwardly revised its forecast for the current year ending March 31.
Revenue is now expected to come in at 228 billion yen (£1.6b / $2.4b), down 15.6 per cent on previous guidance, while profits are forecast to hit 13.5 billion yen (£92m / $144m), 41.6 per cent lower than previously thought.
