The title was rated without any cuts by the BBFC, whose report reveals that the game features more than four hours of cutscenes.
The site confirms that the Resident Evil sequel contains strong violence and gore, but won't publish its full report until the week leading up to the game's launch.
Announced earlier this year, Resident Evil 6 will be available on Xbox 360 and PlayStation 3. A PC release will follow, but has not yet been dated.
The upcoming sequel is set 15 years after the Raccoon City incident and takes place in the infected town of Tall Oaks, as well as China.
The game is Capcom's largest ever production, with more than 600 staff involved in its development.
A demo launched last week for Xbox 360 Dragon's Dogma owners.
The demo, which features three different missions, will remain an Xbox 360 exclusive until September, when it releases for the PS3.
