Krunktis was the first official game event in Krunker. This was event was setup to raise awareness of how easily a virus could be transmitted.

Krunkitis is a fictional virus that spreads through close combat. Specifically, an infected player must kill a healthy player to infect them. In the first day of the infection, over 1000 accounts were infected. Krunkitis has no direct affect on game play, symptoms include a green skin tone, and frequent coughing.

During the Easter weekend, an Easter event along with an egg hunt was announced. 150 easter eggs were hidden on the rotation maps of Krunker. To find an egg, it must be directly damaged by a player, whether it be a bullet or melee attack. The first 5 to find all the eggs were given an animated Unobtainable hat, Vertigo. The first 50 were given a Relic back, Gold n' Egg. The event lasted from Good Friday to the end of Easter, the egg hunt itself was a lot more shorter due to bugs.

The Halloween Event was an event used to celebrate Halloween on Krunker.

This special event was introduced in the update v.3.0.8, along with several new Halloween-themed skins, a new Game-Mode called Raid. This Event marks the beginning of the addition of skins for the much anticipated Season 4. The raids for the event ran between October 11-17, 2020, and again between October 28-31.

For the last days of the event, a speedrun contest was held, with a prize for the fastest time to reach the end of the map. Winners received an Unobtainable Ghostie pet, which was the first pet cosmetic to be introduced to the game.

The Christmas event was introduced in update v.3.3.8, adding a new Christmas Spin, altering the Freight and Subzero maps to look more festive, and changing the Krunker logo to have Christmas lights. The Christmas Spin added ~100 skins, including the contrabands "Present Tamer", "Grinchmas" and "Present Danger". It costed 750 KR to spin, and imitated the Heroic Spin with the exception of not having an Unobtainable.
