I was playing State of Decay earlier. I was playing as Maya, heading from my base in Marshall to Spencer's Mill to bail another survivor out. Along the way, I drove past that burnt-down building with the chain-link fence. It was infested.
I thought I might as well take it out while I was there, so I honked my horn and ran everything that came out down. Maybe fifteen zombies later, I decided getting in close was safe enough, so I did.
After killing almost all the normal zombies, I encountered a feral. Now, the infestation was more or less clear, and I figured it would be a shame to let it re-infest because I ran off. So I fought the feral. It started by kicking my arse, but as I started thinking, 'Just run!', I got a string of good hits in, but never quite managed to pulp its head. Then it turned the tables again.
This time, I knew I was buggered if I didn't run, so I tried to climb over the fence, but it was too late. The feral killed her, and I knew it was down to my having bitten off more than I could chew.
