Cool, I was having a bit of a time figuring things out, lots of stuff doesn't seemed to be explained to well but I am just reaching the point where I am really starting to enjoy it.
My Marcus got killed when trying to pick up the doc and defend the farmhouse, first time I ran in to a juggernaut. I had brought extra ammo for my pistol but didn't realize it was the wrong kind of ammo for my gun until I was in the middle of battling that behemoth. Tried to take him down with some moltov but but only was able to hit him once. He burst inside the house, trapped me in a corner and ripped me in half.
I am sort of excited to see what undead labs will bring in the future now.
