[4] No Gravity is a 3D space shooter that allows players to pilot a spaceship from either a first-person or third-person perspective.

The mobile versions of No Gravity include additional control options, leveraging touch and accelerometer gyroscope functionality for ship maneuvering.

[5][6] In February 2005 realtech VR open sourced No Gravity with the creation of a SourceForge repository.

[10] In 2009 an extended official PSP port, named No Gravity: The Plague of Mind to differentiate from the "classic" older version, was released.

The game was offered by multiple websites as freeware download and reviewed several times over the years.
