Homestuck is an interactive multi-media online comic by Andrew Hussie. The story officially ended on October 25, 2016, but the epilogue was released on April 13, 2019.
On his 13th birthday, John Egbert receives a mysterious new computer game: a beta version of an immersive simulation called Sburb. After he convinces his online friends Rose Lalonde, Dave Strider and Jade Harley to play the game, the four 13-year olds learn that they have unwittingly triggered the apocalypse. To flee the destruction, they each enter a dimension outside of time and space, where they learn that they must win the game to create a new universe.
Winning the game won’t be easy however, along the way they encounter horrors such as: internet trolls who might not be as human as they appear to be, ghosts, aliens, alien ghosts, juggalos, sentient chess people, alternate timelines, plot holes, romantic drama, monsters, eldritch gods, teenaged versions of their parents, a time-travelling demon, and Andrew Hussie himself.
