Capcom's fantasy action role-playing title will be released for Xbox 360 and PS3 in North America on May 22 and across Europe on May 25.
Dragon's Dogma will be packaged with a redeemable token that will allow owners to download the Resident Evil 6 demo.
Xbox 360 users will be able to download the demo on July 3, while PlayStation 3 users will have to wait an additional 60 days to access the same content.
The demo will launch on the PlayStation Network from September 4 in North America and the day after in Europe.
Announced last year, Dragon's Dogma sees three adventurers explore a vast open world to hunt down and destroy a dragon. Players will encounter huge enemies that can only be defeated with tactics and teamwork.
Resident Evil 6, meanwhile, was unveiled earlier this month. Taking place ten years after the Raccoon City incident, it stars Leon Kennedy, Chris Redfield and a mysterious third playable character.
