There is no excuse not to check out Killing Floor 2 this weekend.

Killing Floor 2, the zombie shooter from Tripwire, is celebrating the release of new content with a free weekend and a big sale. From now until March 28, the game will be free to play on both Steam, as well as PS4 for the first time ever.

The free trial can be downloaded in any region, or from Steam if you're on PC. It offers unrestricted access to the content. The game is also on sale both on the PlayStation Store, as well as Steam for 33% off and 50% off respectively.

Earlier this week, the game received a big content update titled The Descent, bringing two new maps and weapons. This is Killing Floor 2's second free update this year, after Tropical Bash in January.

I named Killing Floor 2 one of the best shooters of 2016, a no-fuss zombie shooter that focuses on pure, satisfying mechanics above all else.

Watch the trailer above for the latest content update if you're unfamiliar with the beautiful carnage of Killing Floor. The game supports six players in co-op, or 12 in the Versus mode.
