Decapitation

Decapitation damage bonus and bleed out timer: KFMonster.RemoveHead() [KFMonster.uc].

// Head explodes, causing additional hurty.
if( KFPawn(LastDamagedBy)!=None )
{
    TakeDamage( LastDamageAmount + 0.25 * HealthMax , LastDamagedBy, LastHitLocation, LastMomentum, LastDamagedByType);
}

if( Health > 0 )
{
   BleedOutTime = Level.TimeSeconds +  BleedOutDuration;
}

BleedOutTime usage: KFMonster.Tick() [KMonster.uc].

// If the Zed has been bleeding long enough, make it die
if ( Role == ROLE_Authority && bDecapitated )
{
    if ( BleedOutTime > 0 && Level.TimeSeconds - BleedOutTime >= 0 )
    {
        Died(LastDamagedBy.Controller,class'DamTypeBleedOut',Location);
        BleedOutTime=0;
    }
}

BleedOutDuration is set to 5 in KFMonster.uc, 6 in ZombieBloatBase.uc, ZombieHuskBase.uc, and ZombieScrakeBase.uc, and 7 in ZombieFleshpoundBase.uc

Stunning

Damage requirement for stunning: KFMonster.PlayHit() [KFMonster.uc]

if( Health>0 && Damage>(float(Default.Health)/1.5) )
    FlipOver();

FlipOver's actions: KFMonster.FlipOver() [KFMonster.uc]

// High damage was taken, make em fall over.
function bool FlipOver()
{
    if( Physics==PHYS_Falling )
    {
        SetPhysics(PHYS_Walking);
    }

    bShotAnim = true;
    SetAnimAction('KnockDown');
    Acceleration = vect(0, 0, 0);
    Velocity.X = 0;
    Velocity.Y = 0;
    Controller.GoToState('WaitForAnim');
    KFMonsterController(Controller).bUseFreezeHack = True;
    Return True;
}

Specimens with a blank FlipOver() function cannot be stunned. The ones that have it overloaded and blanked are:

• Crawler
• Bloat
• Siren
• Fleshpound
• Patriarch

Husks

Husks have a second, alternate condition that can trigger a stun. The stun threshold is set to 200 if the weapon is an ebr, lar, or crossbow.

ZombieHusk.PlayHit() [ZombieHusk.uc]

if( Health>0 && Damage>(float(Default.Health)/1.5) )
{
    FlipOver();
}
else if( Health > 0 && (damageType == class'DamTypeCrossbow' || damageType == class'DamTypeCrossbowHeadShot' ||
        damageType == class'DamTypeWinchester' || damageType == class'DamTypeM14EBR')
        &&  Damage > 200 ) // 200 Damage will be a headshot with the Winchester or EBR, or a hit with the Crossbow
{
    FlipOver();
}

Flinching

Even though the variables are bSTUNNED and StunsRemaining, the resulting animation is a flinch, rather than what one would consider a stun. If any one of the conditions is false, a different, shorter hit animation is played, a mini flinch. It is still considered a flinch, but unlike normal flinching, it can be done multiple times to scrakes and fp on Suicidal+.

Flinching code: KFMonster.PlayDirectionalHit() [KFMonster.uc].

if ( Dir dot X > 0.7 || Dir == vect(0,0,0))
{
    if( LastDamagedBy!=none && LastDamageAmount>0 )
    {
        if ( StunsRemaining != 0 && (LastDamageAmount >= (0.5 * default.Health) ||
            (VSize(LastDamagedBy.Location - Location) <= (MeleeRange * 2) && ClassIsChildOf(LastDamagedbyType,class 'DamTypeMelee') &&
             KFPawn(LastDamagedBy) != none && LastDamageAmount > (0.10* default.Health))) )
        {
            SetAnimAction(HitAnims[Rand(3)]);
            bSTUNNED = true;
            SetTimer(StunTime,false);
            StunsRemaining--;
        }
        else
            SetAnimAction(KFHitFront);
    }
}

Scrake

If a scrake has already been flinched or stunned, you cannot perform mini flinches on him because if StunsRemaining is 0, the above code is not called from the scrake code. Also, you cannot perform mini flinches on scrakes with melee weapons because the base damage to trigger either flinch is 150 and melee weapons will trigger a normal flinch when they do a minimum of 100 hp (0.1 * 1000).

ZombieScrake.PlayTakeHit() [ZombieScrake.uc]

if( (Level.Game.GameDifficulty < 5.0 || StunsRemaining != 0) && (Damage>=150 || (DamageType.name=='DamTypeStunNade' && StunChance>3) || (DamageType.name=='DamTypeCrossbowHeadshot' && Damage>=200)) )
    PlayDirectionalHit(HitLocation);
