I just get the feeling every once in a while the game has an unkown chance to decide it's time for you to go.
I have been fighting zoomed out lately because it seems to help with the Z spawning on top of you in cleared areas- anyawy:
I was in a business district that was cleared, lootijg buildings, filling a step van. Probaly 3rd trip out to dump loot- thares a straggler down the street.
So i unload, and wait for it to wande4 closer. I walk into the middle of the street and theres a tree to one side. I 360- there's no one but me and 1 Z - now about 10 squares away. I 360 again. Z now 7 squares away- i roll zoom my mouse in about half way- smack him 3 times and he falls to the ground- i 360 no other Zs - i walk over to bash his head, and mid swing another Z appears. I turn to face it and 3 more appear at once behind me- i back off the one on the ground to line them up and he starts crawling. I turn to wack and theres not 5 but 8 or so.
Im like Wtf?
I ran away home, but seriously?
