"The free Survival Pack adds the new Survival game mode, where players are given time to dig in before fending off unceasing zombie hordes in an attempt to survive as long as possible. Survival Mode is played on 12 new maps--11 being sections of existing levels and 1 created especially for Survival Mode, Lighthouse.

The Survival Pack also brings Versus mode to the final two co-op campaigns, Dead Air and Death Toll. This release coincides with the release of Left 4 Dead: Critics Choice Edition, which contains the original game plus the Survival Pack."

It is 60 years since RCA record company released the first commercial seven-inch single, spinning at 45rpm.

To celebrate the anniversary, BBC News has been given access to a factory that still makes singles.
