Killing Floor 2

Killing Floor 2 is the sequel to Killing Floor. The game follows the events of the original and takes place in continental Europe.
The game was in early access since April 21st, 2015 on Steam and was fully released on November 18th, 2016.

The series main game mode - now aptly named "Survival" - will return. It still consists of up to six players trying to survive waves of zeds with the goal of completing all the waves.
However, many details have changed without touching the popular formula whose high-quality execution made the game stand out among its peers in the first place:

• Graphics, hitboxes and sounds have been improved, and lightning may now play a significant role in choosing your battlefield, as many light sources underground are classified destructible.
• A huge variety of weapons will be available without 'hard' class restrictions.
• Class progression will be less tedious and offer options for customization.
• Choosing a difficulty will not primarily rely on changing the damage and hit point values of the zeds.
  Instead, the zeds will become increasingly dangerous with changes in behavior and new attack variations.
• And more...

The early access versions already includes a level editor, the release will offer full mod support.
Anybody is free to host a Killing Floor 2 dedicated server. The instructions for that can be found here.
