How to do well in CO-OP Survival

First of all here are the basic points you need to know about coop survival:
 * It uses a point system
 * The strong enemies spawn later in the round
 * Tougher enemies give more points
 * Powerups spawn frequently and randomly
 * There is a penalty for dying
 * It has a time limit and whoever has the most points wins

So that's the basics. Simple isn't it? Now let me teach you some slightly more advanced lessons to help you do well.

CO-OP survival is not all about "surviving"
It may sound a bit strange, but if you want to do well it's a good idea to stop thinking about how to "survive" and start thinking about how to "Kill everything the moment it appears". In maps where there are high vantage points such as the Deadly Arena it is a common strategy to stay up high and pick off targets from above. This can be effective to an extent since you can see over a larger area but it should be noted that... So with that in mind remember that the real goal is to notice when an enemy spawns and kill it before everyone else. If you still want to snipe zombies then feel free however the rest of this tutorial will be written assuming that you have given up on that strategy. It's also good to collect those health powerups since they can not only keep you alive to avoid the death penalty, they also give a small point bonus if your health is full.
 * Someone on the ground is closer and can aim at targets quicker
 * Being far away makes it difficult to hit targets with guns that shoot slow projectiles
 * If your up high it's going to be difficult to collect power ups

Gotta Catch'em All! POKEMON! POWERUPS!
Yes I did just use a very cliche sounding phrase and yes you should still follow it. One thing I noticed when playing is that every now and then a player runs out of ammo for their favourite gun. It's always good to keep an eye our for those ammo packs. When your playing you want to use your best guns and running out of ammo can be quite the pickle so switching to your melee weapon to beat everyone to the powerups can help a lot.

Either fast or slow there is no middle ground
"What on earth does that mean!" You ask? Well it's simple. As mentioned previously you want to kill things fast to win and get points fast. Therefore it's logical to use a shotgun/explosives gun since they do a great job at picking off enemies one by one or in groups. If you don't have a good area damage gun like the Crystal Mega Destroyer, are playing in a large open map where shotguns are disadvantageous or simply don't like using shotguns then "Pick up your peacemakers and don't let go of the trigger!". I did say that shotguns can kill things quickly it should also be noted that every time you hit an enemy you get a small amount of points. In other words area damage can kill fast but quick shooting guns can maximize the points you get from each enemy. Pick whichever suits you altho the map your playing on is always important to consider.

Don't think about surviving, JUST DO IT!
I did say that focusing on surviving is bad altho dying a lot is probably a lot worse. There is a fairly large penalty for dying and you have no idea how many times how many times accidentally killing myself has cost me a win ._. If you wanna survive just make sure to "prance around like an idiot" and by that I mean constantly move around, check your back all the time and jump to avoid self damage. This way you won't have enemys sneaking up behind you and even if they did there's a good
