First of all i gotta say i love this game! But as a medic i just like to make a few suggestion towards making Dmg and first aid more realistic :) 1. The normal amount of blood in a adult human being is 5-6 liters. So having it down there would be more accurate. 2. I dont know if the 42c is core body temp or if it is the air around you, im asuming it is the core body temp, Normal would be 37,5-38,0c... 42c is close to permanent brain dmg. (also heat packs in real life only works localy on like hands if you use them inside gloves would need like 20-40 to help core body temp to rise just a little...) 3. The bleed effect is a good addition its just so aggresive! Being slapped by a human being (Zombies) almost always cause an "arterial bleeding" the chance to bleed should be lowered to more realistic. ( guns should always cause bleed effects \ Axes too ) Diffrent bleed effects? the use of tourniquets? 4. Painkillers and Morphine should cause blured vision or atleast some side effect if you use too much.. Spamming painkillers should have aside effect. just one morphine should affect the person.. 5. It is actually possible to start a blood transfusion on yourself ( ive tried just the needle tho ). 6. bandaging just temporary ? why not make some wounds just hard to fix adding a needle and thread to fix the heaviest of wounds. These are just some of my suggestions got loads more but im off to work :) cheers!
