Fourth Day After the Outbreak

Time frame: 4 Days after Outbreak
Phase: Self-Sufficiency

It's only been 4 days and by now, society as you know it has probably been overrun by zombies (if not sooner). Luckily (relatively speaking), you've followed the Protocol and managed to create a small bubble of safety for yourself and anyone else fortunate enough to have followed you. Now that this whole situation is starting to fully sink in, there are two important points to remember:

1) At this stage, Stealth is key.
The initial onset of the Outbreak means that there are mobs of zombies roaming all around you looking for any people to eat/rip apart/convert. Your current Base of Operations (barricaded building) is not equipped to withstand a full rampage of zombies. At most, your Base of Ops can only deter a handful of curious, scavenging zombies. This is why Stealth is key. You need to make sure that the zombies are unaware that your Base of Ops exists. Otherwise, their single-minded brains will cause them to relentlessly attack your base, drawing even more zombies to your location.

Although highly discouraged, if you absolutely must venture outside of your Base of Ops, you must rely on Stealth and Speed. If you are faster than the average person, you should be able to avoid the standard zombie, though will probably be caught by zombies of the rage-filled variety. Also, remember that zombies DO NOT get tired! They will chase you without rest until they've caught you, they've found easier prey, or they've lost the ability to follow you. Avoid drawing attention to yourself and if a mob does find you, DO NOT run back to your Base of Ops. Find a place to hide though you probably still will be found, but at least your Base of Ops won't be overrun.

2) No one is coming to save you.
Local law enforcement and even the Army is fairly ill-equipped to handle a Zombie Outbreak. The best that you can hope for is that they are trying to Quarantine the area affected by the Outbreak to prevent an extinction-level event (though this rarely works). Heck, they may even be behind the Outbreak in the first place, meaning their objective is to clean up after themselves, rather than save you. This means that no one is coming to your rescue, so you are on your own. Also, if you have access to a radio or some form of communication, DO NOT tell them to come to your Base of Ops. They will only open up potential holes in your security and lead mobs of zombies to your location. If you are able to get in contact with other survivors, tell them to find shelter and establish their own Base of Operations. If possible, relay to them as much of the Zombie Outbreak Protocol as possible.
