The phone will allow golf fans to improve their swing via a golfing game.
Those who prefer shoot-'em-ups will be able to use the phone like a gun to shoot the zombies in the mobile version of Sega's House of the Dead.
The phone comes with a tiny motion-control sensor, a computer chip that responds to movement.

Other features include a display screen that allows users to watch TV and can rotate 180 degrees.
It also doubles up as an electronic musical instrument. Users have to select a sound from a menu that includes clapping, tambourine and maracas and shake their phone to create a beat.
It is being recommended for the karaoke market.
The phone will initially be available in Japan only and is due to go on sale in mid-February.
The new gadget could make for interesting people-watching among Japanese commuters, who are able to access their mobiles on the subway.
