According to a Eurogamer report (thanks beemoh) Duke Nukem Forever and Shadows of the Damned have both been rated 18 by the UK's BBFC. The game that no one ever expected to be finished has descriptors for "strong violence, sex, nudity, and language & drug references" - among a laundry list of naughty things. Shinji Mikami and Suda51's game Shadows of the Damned has descriptors for "very strong bloody gore and very strong language." Both games remain intact as in other regions.
Shadows of the Damned, published by Ea in the United States, is set for release on June 1 on Xbox 360 and PS3, according to GameStop. Duke Nukem Forever is published by 2K Games and is set for a release in early May for PC, Xbox 360, and PS3.
At least both games will see the light of day in the UK.
