13 Days in Hell is possibly the scariest flash game I have ever played. Embark in a 13 day slayathon against the soul-less creatures of the underworld. Fight your way out of hell’s kitchen by blasting apart these demons and upgrading your weapons! Clean shots do more damage, and will help you take out more zombies faster.
You must take out all of the zombies as fast as possible, or else they will start chopping away at your character! This might seriously prevent you from completing 13 Days in Hell.
Can you get through all 13 hellish days in this gory shooting game? We hope so; because we’d hate to see these demons have their way with your head. And by that, we mean chopping it off.
