Boatmurdered is a Let's Play of the video game Dwarf Fortress. The Let's Play was collaboratively produced by 14 members of the Something Awful forums from November 2006 to March 2007.
The 14 participants of Boatmurdered were tasked with overseeing the development of an in-game fortress, with each participant managing the fortress for one year of in-game time before relinquishing it to the next player. Boatmurdered is largely presented as a contiguous narrative, with participants recounting gameplay happenings while roleplaying as the fictional leaders of "Boatmurdered", the titular fortress and setting of the Let's Play. As the Let's Play progresses, the fortress experiences a rapid decline; many of its inhabitants suffer violent deaths, and survivors create idiosyncratic works of art that depict the fortress' violent history.
Boatmurdered has been praised as an example of Dwarf Fortress' potential for emergent storytelling, and credited for introducing both Dwarf Fortress and the Let's Play format to a broader audience.
