What’s better than release dates? Nothing, you say? Release hours, man! Valve has decided to indulge us all with the hour during which the free survival pack DLC for Left 4 Dead will be released.

“At roughly 2am PST”, they announced, which means that quite a few gamers will be staying up well through the night to get in on some zombie action. The pack adds the fast-paced survival mode alongside bringing the Dead Air and Death Toll campaigns to Versus.

PC gamers are left in the dust this time, as no specific hour was given. It is “targeted for release later in the day,” noted Valve.
