Capcom has posted a 39.9 per cent profit decline for the sixth months ended September 31.
Profit fell to 1,784 million yen (£13.8m), with game delays, underperforming titles like Lost Planet 2, and the sharp appreciation of the yen largely to blame.
Despite the profit slump, sales increased 4.7 per cent during the same period to 40,706 million yen (£314.7m), with flagship titles Dead Rising 2 and Super Street Fighter IV cited as strong performers.
Capcom said that Dead Rising 2 has surpassed two million copies shipped to retail worldwide, and that the franchise has shipped over four million copies to date.
The company's in the process of releasing multiple DLC packs for the zombie title.
