The pressure is starting to get to you. You have three rounds left in the chamber, not nearly enough to take on the shambling horde that’s trudging towards you. As your back reaches a wall and the looming figures draw near, you twist your head this way and that, looking for any small sign of salvation. An explosive canister sits just meters away. That would be your answer but the undead have reached you, one lunging forward to seize you by the shoulders. The figure’s decaying skin drips flesh onto you as you scramble out of his hold and kick him back into the crowd. It’s bought you a precious few seconds in which you line up your sights with the canister. There’s only enough time for one shot; you have to make it count.
