A hidden special forces unit fights for survival against a mafia wielding biological weapons.
About
Cold rain soaks the containers in the harbor district. The Special Secret Advance Unit, or "SpecOps," has breached the area to stop a mafia arms deal, only to be met by a hideous monstrosity that can no longer be called human. It is a former executive of a rival organization, remodeled by forbidden technology. Faced with a "weapon" possessing superhuman strength and regenerative abilities, the night is dominated by gunpowder smoke and screams. How will you stand against the biological weapons developed by the mafia?

Intro
Cutting through the sound of the heavy rain, a deep roar echoes between the containers. The flashes of firearms illuminate pale mucus splattered across the walls and the shadow of a monster with a distorted human form.
