The Summer Sideshow introduces new content to Killing Floor 2 and new ways to play during the one-month course of its event. The centerpiece is a new circus-themed map, complete with circus freak zeds . There will be a new set of specific objectives for this map, entitled “The Tragic Kingdom”, which unlocks the exclusive Sideshow Hazmat Suit. Players will have to make good use of the two new weapons included in the update: the HZ12 Shotgun is for the Support Perk only and the Centerfire Lever Action is primarily for Sharpshooter and Multi-Perk with Gunslinger.
There will be plenty of other cosmetic items to unlock as well; over 50 different items obtainable by earning tickets during normal gameplay that can be exchanged for things like new face paints. There will be some paid cosmetic DLC as well, that players can purchase through the shop.
