The content of games with a PEGI 3 rating is considered suitable for all age groups. The game should not contain any sounds or pictures that are likely to frighten young children. A very mild form of violence (in a comical context or a childlike setting) is acceptable. No bad language should be heard.
Video games that show violence of a slightly more graphic nature towards fantasy characters or non-realistic violence towards human-like characters would fall in this age category. Sexual innuendo or sexual posturing can be present, while any bad language in this category must be mild. Gambling as it is normally carried out in real life in casinos or gambling halls can also be present (e.g. card games that in real life would be played for money).
Game content with scenes or sounds that can possibly be frightening to younger children should fall in this category. Very mild forms of violence (implied, non-detailed, or non-realistic violence) are acceptable for a game with a PEGI 7 rating.
This rating is applied once the depiction of violence (or sexual activity) reaches a stage that looks the same as would be expected in real life. The use of bad language in games with a PEGI 16 rating can be more extreme, while games of chance, and the use of tobacco, alcohol or illegal drugs can also be present.
The adult classification is applied when the level of violence reaches a stage where it becomes a depiction of gross violence, apparently motiveless killing, or violence towards defenceless characters. The glamorisation of the use of illegal drugs and explicit sexual activity should also fall into this age category.
A U film should be suitable for audiences aged four years and over, although it is impossible to predict what might upset any particular child. U films should be set within a positive framework and should offer reassuring counterbalances to any violence, threat or horror. If a work is particularly suitable for pre-school children, this will be indicated in the BBFCinsight.
General viewing, but some scenes may be unsuitable for young children. A PG film should not unsettle a child aged around eight or older. Unaccompanied children of any age may watch, but parents are advised to consider whether the content may upset younger, or more sensitive, children.
Films classified 12A and video works classified 12 contain material that is not generally suitable for children aged under 12. No one younger than 12 may see a 12A film in a cinema unless accompanied by an adult. Adults planning to take a child under 12 to view a 12A film should consider whether the film is suitable for that child. To help them decide, we recommend that they check the BBFCinsight for that film in advance. No one younger than 12 may rent or buy a 12 rated video work.
No one younger than 15 may rent or buy a 15 rated video work.
No one younger than 18 may rent or buy an 18 rated video work. Adults should be free to choose their own entertainment.

Below Zero is an underwater adventure game set on an alien ocean world. It is a new chapter in the Subnautica universe, and is developed by Unknown Worlds.
Return to planet 4546B
Submerge yourself in an all-new, sub-zero expedition in an arctic region of Planet 4546B. Arriving with little more than your wits and some survival equipment, you set out to investigate what happened to your sister...
Uncover the truth
Alterra left in a hurry after a mysterious incident. Abandoned research stations dot the region. What happened to the scientists who lived and worked here? Logs, items, and databanks scattered among the debris paint a new picture of the incident. With limited resources, you must improvise to survive on your own.
Discover uncharted biomes
Swim beneath the blue-lit, arching expanses of Twisty Bridges. Become mesmerized by the glittering, mammoth crystals of the Crystal Caverns. Clamber up snow covered peaks and venture into the icy caves of Glacial Basin. Maneuver between erupting Thermal Vents to discover ancient alien artifacts. Below Zero presents entirely new environments for you to survive, study, and explore.
Construct habitats and vehicles
Survive the harsh climate by constructing extensive habitats, scavenging for resources, and crafting equipment. Blast across the snowy tundra on a Snowfox hoverbike. Cruise through enchanting and perilous biomes in your modular Seatruck.
Research alien lifeforms
Something undiscovered lurks around every corner. Swim through the giant Titan Holefish, encounter the haunting Shadow Leviathan, and visit the adorable Pengwings. Keep your wits about you. Not all creatures in this strange world are friendly.
Survive the chilly temperatures
Jump in, the water’s warm. The below zero temperatures of this arctic region pose a new threat. New weather conditions blanket above-ground habitats. Craft a toasty cold suit, sip on piping hot coffee, and warm up next to Thermal Lilies to stave off the chill.
An ocean of intrigue
What really happened to your sister? Who were the aliens who came here before? Why were they on this planet? Can we find solace from grief in truth? Below Zero extends the story of the Subnautica universe, diving deep into the mystery introduced in the original game.
About the development team
Below Zero is being created by Unknown Worlds, a small studio that traces its roots back to the 2002 Half-Life mod Natural Selection. It is the same studio that created the original Subnautica. The team is scattered around the globe, from the United States to the United Kingdom, France, Russia, Austria, Australia, Canada, and many more places.
