I am a "better safe than dead" kind of guy myself, but looking at the server logs today a couple of you may not realize the full impact of repeatedly searching areas nearby and running away from all undead that you may discover. There is a little thing called "horde score" (that's what we call it on the back end) that we compute each time you do the following:
1. search a location
2. Find undead
3. Run from undead (instead of kill them)
4. Kill undead
Each time you do any of these things, your horde score can grow. The reason for this is because of what what you are doing represents in the "real world" is you are making noise, entering locations, attracting the attention of the undead, shooting guns, fighting, etc. Basically you are kicking the hornets nest.
You can reduce this score by physically moving to a new location or wait 4 hours with no activity until things settle down.
We have just found a player who shall remain nameless, who has run from danger 228 times, and has over horde score of over 9 million. This means that everywhere he goes there is almost a complete certainty that hundreds of zombies are going to be there to greet him.
Remember, it's smart to run sometimes, but you have to use your head.
