Today thru Monday both PS4 and Xbox One players can play Killing Floor 2 for free. If you haven't had a chance to play this bloodfest of an FPS, then this is your chance.

Here are the new features:

• New Community Map: Endless Lockdown
  • Players can look forward to seeing this fan-made community favorite map officially available for the first time in KILLING FLOOR 2
• New Weapons
  • M99 AMR Sniper Rifle for Sharpshooter
  • Static Strikers for Berserker
  • Doomstick for Support
  • Goreshiv Survivalist Knife
• Weapon Upgrade System
