Weapons guide and information. I will update as soon as possible if I notice something is wrong or find new information that is important Melee damages Zombies have 500 health on normal, and 1,000 in nightmare, so for charging weapons is twice as long; The max charge power is 3.5, and you gain 0.571 per second, you can charge for 6.13 seconds def charge(_dmg): _time = 500 / ( _dmg * 0.571 ) return _time if _time <= 6.13 else False Weapon damage list(the max carrying mass is 10 kg) weapon damage (head) damage charge to kill (casual) mass bat 225 80 3.9 seconds 1.8 kg fire axe 400 95 2.1 seconds 4 kg cleaver 200 75 4.4 seconds 0.8 kg crowbar 320 80 2.7 second 2.2 kg e-tool 230 80 3.8 seconds 2 kg fist 50 25 inf 0 fubar 680 110 1.3 4.5 kg hatchet 280 70 3.1 seconds 0.9 kg kit-knife 140 60 inf 0.5 kg machete 350 80 2.5 seconds 1.2 kg pickaxe 500 90 1.7 3.8 kg pipe lead 320 90 2.7 second 2.15 kg shovel 270 80 3.2 seconds 3.5 kg sledge 600 100 1.5 4 kg wrench 190 70 4.6 seconds 0.8 kg hammer 210 70 4.2 seconds 0.8 kg Firearm Damage Firearm Damage Damage (head) .22 25 300 9mm 35 300 .45 75 600 .556 100 500 .357 125 600 .762 150 600 .308 200 800 12 guag 250 2,000 Damages and health Important and useful information Bleeding does 1 dmg 5% chance of bleeding from injury 15% chance of bleeding from injury when below 45 health bandages stop bleeding and give an additional 15 health medkits give 30 health and stop bleeding if you are Screen turns gray at 35 health (I'm 99% sure) Fire does 1 dmg/unit Molotov fire does 3 dmg/unit Electrocution does 25 dmg/unit (or 100 in some cases) Barricades have 150 health Infection takes 120 seconds to kill Pills stave off the infection for 200 seconds Gene therapy has a 10% chance of blinding you for 60 seconds Zombies can't survive longer than 10 seconds on fire Flare guns do 50 damage, and molotovs do 30 damage Gas cans do 8 damage Zombies can reach 44 inches (3.7 ft [about 1 meter]) Molotov damage radius is 96 inches (8 ft [2.4 m]) Molotov burn frequency is 0.5 seconds Molotov damage duration is 20 seconds Grenade blast radius is 256 inches (21.3 ft [6.5 m]) TNT blast radius is 512 inches (42.7 ft [13 m]) TNT shake screen radius is 2048 inches (170.7 ft [52 m]) Probability of zombie dropping loot 10% List of zombie damages Bites always do 15 Hits always do 15 from regular zombies Runners do 20 and 40 damage for 1 and 2 hands respectively Kids do 8 and 16 damage for 1 and 2 hands respectively Here is health fraction of zombies Runner Kid Crawler 0.7 0.2 Always 50 hp Mathematics Probability of getting infected fₘ = infection chance modifier (0.975 on casual and 0.14 on nightmare) fₕ = health as a fraction (You are twice as likely to get infected in survival mode) P = (1 - (fₕ ⋅ fₘ))² Fall damage My calculator (theoretical)[xyzpw.github.io] My theory is fall damage is (25/55) ⋅ (V - 480) Because half-life has the same formula, but the multiplication factor is different, and it matches up with maximum fall velocity to 100 dmg and minimum 0; which, g = 20 m/s^2 Stamina I've messed around with crouching and it never seems to increase stamina regain, so that's most likely a myth. Stamina cost list Stamina cost is 2-fold when bleeding Shove cost 20 Jump cost 20 12 per second when sprinting Not moving regain rate 12 Regain rate crouch 9 Regain rate moving 6 Light breathing plays at 80 stamina Medium breathing plays at 60 stamina Heavy breathing plays at 40 stamina Maximum stamina is 130
