A good loadout for a horror movie would be
- A flashlight (with extra batteries)
- Night vision goggles in case the flashlight fails
- Stab proof clothing
- A slim bulletproof vest
- A tactical helmet
- Sturdy, water resistant footwear
- A semi-automatic pistol(faster reload) with a fairly large and powerful round
- Several magazines for the pistol
- A powerful backup revolver in case the semi-automatic pistol jams
- A switchblade knife (easy to carry and deploy)
- A wound care kit
- A satellite phone(charged) with a heavy duty battery
- A body cam (with extra batteries) to record everything
And park your car near the entrance in a great place, and make sure it’s got some decent horsepower to get away quickly. If you don’t have a powerful car, then rent a Ford Mustang GT or something
