In Space with Markiplier

In Space With Markiplier is an interactive video adventure published as a YouTube Original, starring Mark Fischbach, aka Markiplier. It is the second commissioned special Fischbach did for YouTube, after A Heist With Markiplier, as well as one of the final YouTube Originals before the division was shut down.

This adventure takes the viewer to space, where they assume command of the ship Invincible II and things quickly go awry, with each successive video allowing the player to make a choice that eventually takes them to one of five endings. The story is continued in In Space With Markiplier: Part 2.
