Last week, The Amber Alert network released a truly WTF, fearmongering gun porn PSA tagged, "You don't need a gun to protect your kids." (But it does help). Because it's four people with assault rifles, you know what's next.
YouTube user E3Vidz (for Eternal Entertainment Enterprises, not the expo) spotted the opening and ran with it, going all Lifetime Movie of the Week on Left 4 Dead. I'm not sure either video has much of a message but the second one makes a little more sense to me.
Left 4 Dead 3: Not Without My Daughter. Make it happen, Valve.
