ZED Time in Killing Floor 2 happen during killing ZED s or killing players. If ZED dies under other circumstances his death also may cause ZED Time .

ZED Time duration is 3 seconds.

ZED Time is a timer (float value 3.0000). It goes down from 3.0000 to 0 and resets back to 3.0000 as long as player's perk can do that.

Note 1: ZED Time cannot really be extended by certain amount of seconds. Instead it gets reset. Non-commando perk can reset ZED Time only once. Commando perk can reset it up to 6 times: levels 1-4 - 1 reset (just like every other perk), levels 5-9 - 2 resets, levels 9-14 - 3 resets, levels 15-19 - 4 resets, levels 20-24 - 5 resets, level 25 - 6 resets. ZED Time will be reset as soon as another ZED will be killed. For example Support can accidently reset ZED Time just because his shotgun has killed few ZED s by penetration.

ZED Time slows world to 20% of its normal speed (i.e. by 5 times).

Minimum interval between ZED Time s is 10 seconds.

Base chances to get ZED Time are:

Player kills ZED (within 300 units of range) = 2.5%.
Player kills ZED (range > 300 units) = 5%.
ZED kills player or another ZED = 3%.
Commando extension = 100%.
Boss dies = 100% (duration - 6 seconds).

In addition to base chances following events also has their chances to cause ZED Time :

Player kills 4 or more ZED s with an explosion = 5%.
Player kills 2-3 ZED s with an explosion = 3%.
Player kills ZED with a headshot (within 50 units) = 5%.
Player kills ZED with a headshot (range > 50 units) = 3%.

Note 2: These chances are separate. You have 5% chance to get ZED Time when killing a ZED and same time you have 5% chance to get ZED Time upon headshot.

Following chances increases in time if time passed since the last ZED Time is:

10 seconds - no ZED Time chance.
10-30 seconds - normal chance.
30-60 seconds - 2 times better chances (x2).
60+ seconds - 4 times better chances (x4).

How it works:

With each ZED / Player killed, game roll the dice (uses FRand() function that returns random float value between 0 and 1). Then checks if this value is greater or less than base chance (3% = 0.03, 5% = 0.05 etc.). If this value is less than base chance, ZED Time begins.
