Surviving past round 5

If you wanna survive in Zombies past round 5, 10, 20, maybe 40 even? You better listen, I can survive on any zombies map and i can do it well.
By the time you get to round 5. You should always have a weapon other then your pistol. Buy a weapon off the wall or from the mystery box!! You will not survive if you do not! It doesn't matter what it is. Now the easy way to do this is to look for any weapon off the wall. These weapons will range anywhere from 500 points to 1500. Try to get an automatic weapon. They cost usually around 1000-1200 but they are well worth your points.
Or if you can find it you can hit the mystery box if you can find it. It's literally a box that has two glowing question marks on it. You might need to open a door or two or even three to get to it. (keep in mind the box costs 950 points) Gambling for a random gun from the box is a gamble because you could get a very bad weapon or you could get a very good one hence the name "Mystery Box".
After you have a good weapon, save up for juggernog. This perk will increase your max health by 250%.
Without it, your a dead man as zombies can get you down in 2 hits. But with it, it will take 5 hits for the zombies can get you down. And yes, your health does regenerate.
On the next post we will be discussing how to run trains, which is running around the zombies and letting them follow you instead of standing still and getting over ran when more then 20 zombies are all over the place. This is very important if you want to go past round 15 or 20 on any map.
