Still not sorted your Halloween plans? If you fancy being scared silly and getting plenty of exercise while you're at it, join Undead Escapes' immersive zombie apocalypse game this weekend.
Here's the scenario: you and a team of mates are invited to investigate a rogue arms company that has been building biological weapons. Unfortunately, things don't go to plan, and the walking dead escape. So your mission is to survive by dodging the infected on the streets of London while attempting to find the elusive Patient Zero.
After two to three hours of running for your life, there's an after-party where you can catch your breath, have a stiff drink and mingle with fellow players (both the infected and survivors are welcome).
But be warned: attempting to survive an apocalypse might just show you who your real friends are.
Patient Zero will take place on October 28 and 29 at Queen Elizabeth Olympic Park. Tickets are £49.
After-party finishing times: Fri – 3am, Sat – 2am. Closest station: Hackney Wick.
