Killing Floor 2 1.58 Patch notes – October 5, 2021

Day of the Zed

  • Welcome boys and girls to the Day of the Zed! Are you prepared to visit Netherhold and unveil all the secrets of this bastion of torture? Discover the hidden passages and maybe you will be able to survive. Speaking of surviving… two new weekly modes that will test the skills of the most veteran mercs, especially Abandon All Hope, our ultimate challenge for those who see Hell on Earth as child’s play. For those who can’t handle the heat of AOH, perhaps journeying to the Wild West London will sate your inner Cowboy spirit. Only Gunslingers and Sharpshooters may apply. Finally, the Horzine devs have some offerings that may help you with these challenges, two new HRG weapons ready and loaded, the electrifying HRG Disruptor and the explosive HRG Tommy Boom.

Designer Notes :

We included the option of purchasing armor in portions to allow the mercs to have more flexibility and control in the trader menu. We think that it will be especially useful in situations when you have few dosh to spend and need to distribute it between ammo, armor and grenades.

Some time ago the 9mm was excluded from the weapon rotation of the quick swap button, as part of a quality of life improvement. Some players appreciated this change but others missed the previous configuration. So now we have included it as a configurable option, so any player can select the one that prefers.

We added the Discount UI optimization and the More Transparent Drop Percentages just to increase the user experience of the store and the inventory in general.

The Mine Reconstructor was underperforming compared to other Field Medic weapons. It has not found a gap in the weapon loadout for most medics, so we made some adjustments to tune up some general stats, aiming to place it in a better position and making its unique mine mechanic to shine more.

We also made some adjustments in the special heavy attack of the Hemoclobber. We increased the damage but reduced the healing of the explosion and the magazine size. So the gas explosions will be less frequent, more powerful against enemies but less efficient in terms of healing.

Finally, two SWAT perk skills had some functionality tweaks that should improve their performance and viability. Tactical Movement will offer even more movement capacities and Close Combat Training will also improve the melee (bash attack) of all SWAT weapons.
