Charlie Higson's Enemy - Early Map Sketch 2

The style of the Sicko's was very important to Charlie; he didn't want them to look too much like generic - possibly supernatural (rotting, animated corpses 'brought back to life') - 'zombies'.

These are living adult humans in a horrible state of advanced illness that – as it's destroyed their personalities and mental faculties in the sense of controlling their terrible urges to violence and cannibalism – manifests in shocking, poisonous distortions of their physical form.

Here the prototype 'Sicko' was possibly a little too familiarly zombie-looking, though the idea that his dreadful hunger is making him begin to eat the Map itself was fun at the time.
