The Gunner

From publisher blurb:

I Love the Smell of Gunpowder In the Morning...

Ever smelt that intoxicating smell of a spent round? Ever feel the “thud thud thud” of shells hitting the ground while you cut down fourteen men with your gun? It’s a dream come true and if you missed that dream- you’ve still got time to rectify that.

Gunners can amp themselves up, whipping themselves into a frenzy and this gun-madness can infuse their bullets with a sort of unnatural quality. Some say they are naturally psychic or unwitting servants of a god of slaughter but they just keep pulling that trigger until their enemies stop moving.
