A Spec Ops: The Line demo is out now, 2K Games has announced.

It’s currently available to all PlayStation 3 users and Xbox Live Gold subscribers, but will open up to all Xbox Live members on May 15.

The demo includes portions of two early chapters of the Spec Ops campaign, which sees Captain Martin Walker search for Colonel John Konrad and his missing battalion in war-torn Dubai.

If that name sounds familiar, it’s because the game is a modern adaptation of Joseph Conrad's classic novella Heart of Darkness, which was famously brought to the big screen by Francis Ford Coppola as Apocalypse Now in 1979.

Spec Ops: The Line launches on June 29 for PC, PlayStation 3 and Xbox 360.
