Shall we give it a blast tonight?
I assume our server(s) will need updating.
Our servers have been updated.
Looks like the new maps are coming in with "Chapter 13" names, whereas the last official update was for "No Mercy" and came in at "Chapter 8".
Now we have 5 old school L4D campaigns, one of which has been converted and the other four scheduled to be released, this takes us up to "Chapter 12", so that's why it's '13'.
Anyone fancy a rumble tonight?
