Because all the game's categories are single player only, I don't suppose why we shouldn't add a Multiplayer option for those who want to run with our friends or family.

I'd agree with a multiplayer feature too

Me too I want play With @ZEUS1786

SRC is kinda a horrible website in terms of reformatting, so that's why we haven't added new categories for a while. We do track a bunch of extra categories here though https://docs.google.com/spreadsheets/d/1G7C8So7I3_Nd11MNhbE_8NHk8s6FO8sf1WB8DbJx4Rc/edit#gid=0

If someone records a multiplayer run and sends us proof, then we'll probably add it to the google doc. Don't let multiplayer not being on the main board stop you from doing runs though,

Where do I go to play multi-player in the first place?

At the beggining of the run, you select how many people are playing. At that point, you can select 2,3 or 4 if you are playing woth more than 1 person.

This occurs as soon as you select a new file.
