I always get stumped at this stage. When I built Union I had plenty of time to come up with a title as I didn't announce it until shortly before its release. However, I've decided to work differently with my Left 4 Dead levels as I'm having to look to the multiplayer community for testing much earlier on in the development process. So I need a name.
Last time I looked to the Interlopers community for help with naming Corn of the Dead (which I'm very happy with). Now I need something for my new L4D2 campaign, which currently has the working title 'There and Back'. It focuses on the survivors being dropped off by helicopter at a CEDA Evacuation Center, only to find it overrun by infected. The survivors must reach the military base nearby and use its facilities to call the helicopter back, before making a mad dash back to the heli-pad at the start for extraction.
