BINARY DOMAIN is a third person perspective squad shooter. Set in Tokyo in 2080, the player assumes the role of Dan 'The Survivor', a member of a special forces unit attached to the International Robot Technology Executive Office. The world has come to rely on robot technology, but the robots have become self-aware and have turned on their human masters. The game was classified '15' for strong violence.

The BBFC's Guidelines at '15' state 'Violence may be strong but should not dwell on the infliction of pain or injury. The strongest gory images are unlikely to be acceptable. Strong sadistic or sexualised violence is also unlikely to be acceptable'. The player-controlled character can carry up to four different types of weapon, including pistols, shotguns, assault rifles, chainguns, sniper rifles, rocket-propelled grenades, and fragmentation grades. Opponents are invariably robots (of the 'Terminator' variety, with glowing red eyes). Shooting them causes bits to drop off, including legs and heads, and they will eventually explode and disappear from the screen. The player-controlled character can also perform a melee attack, during which he lashes out with whatever weapon he is carrying. For the most part, however, there is neither blood nor injury detail and it is not possible to mutilate fallen robots or to inflict any other form of post-mortem damage. Although it is possible to shoot friendly characters, they are not harmed: they merely complain and the player loses 'trust'. Some of the non-interactive 'cut scenes' do include blood spurts as the player-controlled character, his colleagues, or hybrid robots (including 'Hollow Children' - half human, half robot) are shot. There are, however, no particularly strong gory images and none of the violence is sadistic or sexualised. The player-controlled character can be harmed by incoming fire and the screen increasingly turns red to signify the degree of health loss. He can be revived by injecting himself in the chest with a syringe from a 'health pack'. Health packs can be found littered around the playing environment or can be 'purchased', as can weapons, ammunition and skill upgrades, from special kiosks. Other members of the squad also carry a limited number of heath packs but when these have all been used the screen will go pale as the player-controlled character dies, to be respawned at the last save point.

BINARY DOMAIN includes some mild to moderate sexual banter that would have been permissible at '12'. The game also contains infrequent strong language and frequent moderate language, including the terms 'prick' and 'whore'.
