If you're itching for a new shooter to play, you'll be pleased to hear you can try Killing Floor 2 for free between now and Monday, June 25 on PlayStation 4 and Xbox One. Killing Floor 2 is a co-op shooter that takes place in a zombie-infested version of Europe that's seen civilization collapse. Despite the downfall of governments and the general unrest that's going on, a group of survivors is trying eradicate the "zeds" and rebuild society.

In GameSpot's 8/10 Killing Floor 2 review, we said, "If the expansive suite of Call of Duty multiplayer modes is analogous to a buffet, Killing Floor 2's offerings are a hearty plate of meat and potatoes. The game hones in on the basic appeal of killing zombies without the complications of reaching waypoints or setting up intricate fortifications. Yet Killing Floor 2's strongest asset is in its simple yet effective combat--Tripwire could substitute the zeds for robots or Nazis and still have a solid shooter on its hands."
