Picking up either Street Fighter IV or any of the Sonic the Hedgehog titles from the App Store will see all the proceeds from the app donated straight to charity to help rescuers in Japan until March 20th.
The games are available for download at a discounted price now, going for between £0.79 (for Sonic Spinball and Street Fighter) and £2.39 (for Sonic the Hedgehog IV episode I). Also available are Sonic the Hedgehog 1 and 2, priced at £1.19 and £1.17, respectively.
"Our deepest thoughts and prayers are with the people who were caught in the tragic Tohoku Region Earthquake" said Capcom via the App Store. "As a Japanese gaming company, starting from March 15th through March 22nd we are going to drop the price of Street Fighter IV globally and donate all the sales to public charity."
Both Street Fighter and the Sonic the Hedgehog series have claims to being THE iconic titles from the days of Sega's Megadrive system, with Sonic 2 recognised as the console's best-selling game ever, shifting over six million copies. Whether for charity or nostalgia factor, retro-gamers have until Sunday 20th March to do their bit.
