Fallout: London has narrowed its release window down to 2023, with the announcement coming in a new trailer that showed off more of the mod and its British post-apocalypse. A Fallout 4 mod, Fallout: London is an ambitious fan project that its development team says allows for non-US cultures to be explored and to see what impact the Resource Wars had on Britain and its class-structured society.

The project also boasts some big-name voice actors in the form of Colin Baker and Sylvester McCoy, who played the Sixth and Seventh Doctors respectively in the long-running sci-fi series Doctor Who. Both actors have reprised those roles in numerous Doctor Who audio adventures produced by Big Finish, giving them plenty of voice acting experience over the years.

Fallout: London is set 50 years before the events of Fallout 4 and is aiming to create a grittier experience that emphasizes the use of melee weapons over firearms. You can see more of what Fallout: London has to offer in the video below, which shows off surviving British landmarks such as Big Ben and the Tower of the London.
