Survival in Post Trauma is about more than just avoiding enemies; it's about intelligent resource management and environmental awareness. Here are some advanced tips:

- Sound is Your Ally: Pay close attention to ambient sounds. Distant growls, creaks, or footsteps can alert you to nearby threats before they become visible. Use headphones for a more immersive and tactical advantage.
- Flashlight Discipline: While essential, a constantly on flashlight can attract attention. Learn to quickly toggle it on and off ('F') to conserve batteries and remain hidden. Use the Lighter for quick glances in very dark, seemingly safe areas.
- Environmental Traps: Some areas have environmental hazards that can be used against enemies, such as unstable shelves, leaky pipes, or electrical panels. Lure enemies into these areas and interact with the environment to damage or stun them.
- Backtracking for Resources: If you're critically low on health or ammo, consider carefully backtracking to previously cleared areas. Sometimes, new items or enemies might have spawned, or you might have missed something. However, be aware that backtracking can also be dangerous.
- Save Point Strategy: Don't just save when you're about to die. Save after solving a complex puzzle, finding a crucial item, or clearing a particularly dangerous area. If save resources are limited, prioritize saving before major boss fights or unknown territories.
These strategies, combined with basic stealth and evasion, will significantly increase your chances of survival.
