Instantly die from:Within 100 Hammer Units (1.91m or 6.27 ft), shotguns deal 5 times their normal damage to any Common Infected, and received body damage is modified by the game's difficulty:She receives 5 times damage from shotguns at point blank range (except on Realism), and received body damage is modified by the game's difficulty:He receives same damage everywhere, takes only 85% damage from automatic shotguns in L4D2 and 300% damage from the Grenade Launcher.Different weapons have different damage drop-off over distance characteristics, most obviously linked to the caliber of the weapon. Of note: (excluding shotguns) pistols have the highest damage drop-off (up to 25%), scoped rifles and the Grenade Launcher's projectile have no damage drop-off. Splash damage suffers damage drop-off relative to the center of the explosion.A simple attack which pushes the target back at arms length distance and stuns them for a small amount of time (1-3 seconds, depending on Infected type and resulting animation).Extremely useful in defense against large hordes of Common Infected and rescuing other Survivors caught by Hunters, Smokers, or Jockeys (but not Chargers, which are not affected by such attacks).Fatigue sets in after 5 melee attacks, a Survivor is obliged to wait 2-3 seconds until this attack can be used again. Repetitive use of a melee attack thus incurs a series of short time-out intervals to stimulate the body's need to regather its strength for the next strenuous exertion. Only use melee attacks when it is essential to better manage your fatigue.Shove(Melee/M2) back the boomer before shooting if near, shoot if far.Shove(Melee/M2) back the spitter before shooting if near. shoot if far and stay away from spit.
