Ghouls are gravediggers that feed on the bodies of the dead. Ghouls are often found on battlefields that are littered with rotten corpses of people who were never buried. 'Our version of the ghouls is slightly different – it’s a mix of the ghouls and other monsters that are present in short stories. We decided to make them a bit bigger, nastier, alien like type of herd monsters,' Tomasz Baginski explains.
