I broke my legs yesterday near the NEAF. Today I crawled back to the airfield to find a morphine or sticks. The airfield was not looted, so there where zombies. I was light green energized, light green hydrated and helathy. So when a zombie sees me and I have broken legs, I stand up and wait for it to reach me so I can kill it with my firefighter axe. I did this with 2 or 3 zombies, but when the last one reached me he hit me once and I died. The other zombies did not hit me, just the last one!
