Metu Caligine

Kill victims of experiments with melee weapons or firearms, (you must find them) it can save your life, but remember the ammo can run out, an accurate headshot will solve this problem, also use auxiliary items, flashlights and do not forget about the batteries, they can run out at the most inopportune moment! inspect every room, maybe there are shields for turning on the electricity (this will obviously be very useful). Also, do not forget to take food and various medications, they will help you...
