The main thing to understand about weather effects is that they're not currently part of the core experience (which actually makes sense for this type of indoor-focused horror gameplay). Instead of dynamic weather changing things up, the real challenge comes from managing your flashlight and dealing with the environmental hazards that are built into each location. You'll find that visibility and atmosphere are carefully incorporated through the map design itself, creating tension without needing rain or fog effects.

Something interesting to consider - while mods might add weather features down the line, the base game really focuses on physics-based interactions and monster encounters (this design choice helps keep the focus on immediate threats rather than environmental distractions). The intensity comes from the way areas are laid out and how the difficulty ramps up naturally as you progress. Good to know that your visibility challenges will mainly come from managing your light sources and staying aware of your surroundings (keeping track of your flashlight battery is crucial since it's your main tool for spotting dangers). What makes this approach work is how it keeps the horror elements consistent and predictable enough to plan around, while still maintaining that edge-of-your-seat tension throughout each run.
