Tripwire Interactive are currently running the Tidal Terror event for Killing Floor 2.

Tidal Terror is the latest version of Killing Floor 2‘s big annual summer event and update, and it lasts until July 12th.

The event centers on Rig, a new map depicting a massive oil rig in the ocean that has been overrun with Zed. As with all summer updates, players can enjoy weekly events and modes, as well as nautical-themed skins that can be purchased in the in-game store.

The update also includes some new weapons: the Reducto Ray for the Survivalist, the Sentinel for the Commando, the HGR Crossboom for the Demolitionist, and the HGR Head Hunter for the Sharpshooter.

Here’s a rundown on the new event:

Killing Floor 2 – Tidal Terror Event

Off the coast of Scotland in the East Shetland Basin of the North Sea, we’ve located a secret research lab hidden away in an oil drilling rig. We can only imagine what horrors the Patriarch and his cohorts have been up to here in this remote location. By the way, if you are one of those people who like to try different weapons, we have a new weekly mode for you, Arsenal Ascent, in which you will be swapping weapons as you kill Zeds. And if that weren’t enough, the Horzine Research Group just released two new products, the HRG Head Hunter and the HRG Crossboom, for Sharpshooter and Demolitionist mercs respectively. Hurry up and take a look!
