I think i will go for hours about this one. when you first hear of an Apocalypse , you want to determine how wide spread it is. keep in mind the the government will likely deny it until the end. If in your judgement it will make it to you, you want to aquire things that you will need in advance. keep in mind that money will mean nothing once the government falls. use the black market/deep web if necessary. you probably want to leave the city's those have a lot of obstacles. you can get ambushed and have less distance pick off the zombie's before you have to run. you must also keep in mind that, this is not minecraft, their are not unlimited zombie's, their are only 7 billion people in this world. eventually they will die, weather it be by your hands. or another brave survivor.
I haven't really thought further than this. if i make it to the end. my soul will rest easy.
remember pack for an armageddon.
nuclear detonation/EMP is also likely (pack accordingly)
Theirs plenty of survival strategy's that aren't PG rated that I could add to this.
