Heartbeat (sometimes Heart Beat) was a Japanese video game developer, famous for developing the sixth and seventh installments of the Dragon Quest series. Heartbeat also developed a remake of Dragon Quest IV. Plans to localize this remake in North America were halted when the employees of Heartbeat decided to take a sabbatical. The company stated its reason was "the raise of development costs," despite the massive financial success of its games. The company is currently non-existent, but several of its members have created Genius Sonority, a company that develops games for Nintendo.
