ZOMBIES: In this “one part haunted house, and two parts interactive theatre,” you must get to the vaccine before the zombies get to you. How will you bring an end to the zombie invasion? With Nerf guns of course! Fort Fringe (607 New York Avenue NW). Shows begin in 20 minute intervals between 7-11 p.m. $35

MYSTERY MOVIE: The D.C. Public Library and the Museum of Science Fiction are co-hosting a science fiction film festival, though you won’t know what movie is being screened until it begins playing. Clues are given on the MOSF Facebook page. Martin Luther King Jr. Memorial Library (901 G Street NW) 6-9 p.m. Free, but RSVP here

EDGAR ALLAN POE: To celebrate Halloween, Kramerbooks and Hillyer Art Space are hosting a marathon reading of The Tell-Tale Heart and The Raven. You can sign-up to read, or simply be a spectator. Either way, you’ll want to arrive in a costume, as there will be a prize for the best one. Hillyer Art Space (9 Hillyer Court NW) 6:30-8:30 p.m. Free, but donations encouraged.
