First of you will need a survival pack. Specifics can be found here. If you're lazy to get the full set, like me, I'd say have a torchlight, swiss army knife, lighter and a first aid kit. Thats the minimum you should have.
Then, depending on the situation, it would be wise to form a team. Call your friends up. Working with people you are familiar with would be great. Try to form a well-rounded team based on the different classes and of course, stay away from the snitches and leechers.
Once you have a team, it would be good to have a base of operations. A good defensible base with multiple escape routes would be good. Fortify and stay safe.
If you are Asian, like me, you will 99% of the time become a jabroni (so you will die somehow, somewhere) unless you are Japanese. The only people who have the highest chance of survival are Caucasians. Besides that...
You have to be a freaking handsome/beautiful person. The next best candidates for survival are these category of people. The charming looks are a natural repellent of death. If you aren't well-endowed, just take everyday as it comes. Each day will be a blessing. Of course being good looking also means your partner must be good looking.
Depending on how merciless or practical you are, it would be wise not to have your spouse in your team. Yes. NO SPOUSE IN YOUR TEAM. Why? Unless your spouse is the ultimate survivor, love can only screw your chances of surviving. The story is the same all the time. A plan is executed and somehow, somewhere the plan goes awry. Then a spouse gets into 1) a life threatening situation or 2) a fatal accident. Since love prevails, the other love bird would in the case of 1) jump to the rescue and 2) become depressed and demoralized which in turn leads to carelessness and eventually death. In some cases, other jabronis are dragged to hell as well. So if you really want to survive, either get a kick ass spouse or just put a bullet in your spouse's head and save yourself from future misery. If love prevails, then don't say I didn't warn you. Of course if you and your spouse fall under the category of good looking people, then you stand a fantastic chance of survival.
So that about covers most of the general tips for survival. In the next post, we will look at survival tips in specific situations.
