Spacewalk is a networked interactive experience about taking a space walk outside of the International Space Station. Players collectively take on the role of astronauts navigating and exploring the structure of the space station. Spacewalk is an interactive experiment in alternative control schemes, free-form play, virtual embodiment, and metagame communication.

Spacewalk was designed and developed by Richard Emms over the course of five days as an assignment for USC's Interactive Media MFA program. Although it connects to other players across the internet, it is intended to be played with people in the same physical space. It is now compatible with the Oculus Rift.

Spacewalk has been featured on NBC News, The Penny Arcade Report, and Rock, Paper, Shotgun.
