In this outbreak, Zeds increase their health, size, and reach when they hit players or are affected by certain Zed abilities.
When joining online Servers to play the Weekly not long after it has switched, the Server may still be running the Outbreak from the prior week if they haven't refreshed yet, but completing it will earn you the rewards for the current week. The game will cycle through each Outbreak before repeating any, so if you missed a prize you won't see it again for at least 7 weeks. Outbreaks are intended for Perks that are level 15+, and most are played on Hard or Suicidal Difficulty and the Medium Game Length. To play the current Outbreak, select 'Weekly' from the Game Mode list. The gameplay mechanics of certain Outbreaks can also appear for a single wave in Endless Mode as a 'Special Wave.' If you already have the cosmetic reward, you can still earn the Vosh reward as long as you haven't already gotten it that week. Completing a Weekly Outbreak will earn you a cosmetic Rewards and 500,000 Vosh (which is enough for a new Vault Crate). It changes over on Tuesday evenings (US time). There are currently 8 possible Outbreaks, with one available each week. They were introduced as part of the Summer Sideshow 2017 update. Weekly Outbreaks are a feature in Killing Floor 2 that add some variety to the standard Survival Mode.
