A meditative Aussie game called Expand is coming to PlayStation 4 next week.

The game was created by Adelaide's Chris Johnson and Chris Larkin, and according to Kotaku AU, it's one of the country's unplayed gems.

That same site also has an incredible feature on the game, which contrasts its development against that of Hacknet. The creators of the two games are close friends, and while one went on to sell half a million copies, the other languished.

IGN also reckons Expand is worth a look, praising its soundtrack, strikingly sparse visuals, and the way its simple gameplay evolves.

Expand is out on PS4 on October 3.
