You may not know or be somewhat familar with a cert in planetside 2, Well a cert can buy you almost anything in the game other then comsmetics for your character. Certs are your friend and if you do good fighting or anyways get many kills before your death then you can make at the very least 10-20 certs before your death. Now to get 20 certs before you die you have to be good. Don't be a noob who use SC and has all this good gear for your lvl and you don't even know how to use it. If you don't know how to use it, Then your like a idiot in the battle. Heck, I bet that person who just started and has the reagular weapon could kill you with beginner luck for buying items that you don't even know how to use.
Yeah, I know what your thinking, your thinking that i don't know what I am talking about and buying tha gear is making you better. Well if you buy a weapon that if you can use to its full potientail then you could be making plenty of certs but most people don't know how to use there jetpack to its full advantage and there heavy assult shield either.

When you are launch into battle you may usually head to any battle even if there is only one enemy. One i would suggest not doing that if you like seeing that gear in the store and how expensive it is you are going to need to go to a -Larger Battle-.
In the Map, (press letter M on keyboard) you can hover your pointer over each region and on those regions you can see how many men are there, usually in the bottom right corner it should show you the percent of players there and it would have 1-12, 20-40 or 45+, if it has 20-40 or 45+ then that will have some good action and enemies, E+Y=C, E= enemy, Y= you, and C= Certs, You kill the enemy and you get Certs the more killed before you died the more certs you gain Now with more certs you can buy yourself attachments and better weapons. This will help you farm more certs.

Well what you need is SKILL. Skill on how to move out of fire and how to control the inflitrator cloak. Some people can take this from other fps games they have played, But not all. Also taking risk is a big thing, its a video game so if you get shot you ain't going to die in real life. taking risk in getting killed can get you far more kills then just slowly moving around a corner. inflitrators are good at doing behind kills becasue they can go invisiable.
I will cover class importantance next

Classes play a major role in cert income because differnt classes can do and have different weapons and abilitys. Like medics, they can heal and revive their allies which helps their allies advance but also gives you certs for healing and reviving them. Engineers get certs for repairing vechicles or maxs. These two classes are more noob friendly in my experience because you really don't have to be exactly in the frontline to get these certs.
The inflitrator is a good class if you get him his empire base smg and put more attachments on it. With his cloak and that smg he can get a kill, cloak and reload, get another kill, and repeat which that works usually.
The light assault is good for getting to enemies or hard to reach places. If you get him a good weapon and have atleast some good skill you could be slaughtering enemies left and right.
The Heavy Assualt is good for taking heavy damage and if you buy him a lmg and put some good attachments on it he could harvest kills and get certs
The max unit is good depending on the weapons. If he has close range then hopefully your using him in a close combat envoirment. If he has anti air or anti vechicle then i hope your using him in a more vechicle envoirment.

Note: planning in future to add name of weapons after i tryed them for each faction, my primary faction is NC so please don't get on me if say something not correct for a faction, if its not correct tell me in the commets. Thank you

Okay so the inflitrator class is that class that sometimes I dislike because ina huge fight its hard to see an invisable man running behind you or in the side of your vision. Well that invisable man doesn't always just carry a sniper, Usually the faction specific smgs are pretty good in using adn using the correct tactic helps you imcrease the humber of kills.
Now a good tactic for the inflitrator is to place one of your motion sensor next to a point and then guard it from a postion that the enemy does not know you are at. This can keep you safe from being killed but get a sustantial amount of kills.
Now another good tactic for inflitrator is to attack when not cloak by shooting the hostile before he spots you ( may seem basic but its important) then cloak to reload and keep shooting them when they may come around.
If your an offensive inflitrator like me then what i do is attack by going to the point and usually around the hostile base i pick off the loose ends then work on the guys hiding in groups.


Will add more...

Now the light Assualt class is good for getting to hard to reach places. you might've read this in the previous section but this will have some more details on the light assualt.
First off when you are attacking a heavly populated guard tower base you can use the jet pack to get to the first level of the base passing up the stairs and not getting shot that way. When your up there use the shotgun that you get for free. Don't think, well the developers gave me a shotgun, it must not be that good if their not even charging some certs for it. No those shotguns they let you use are actually pretty good. When up on the second floor you can target differnt hostiles because most time their looking down on your buddies shooting them. Hop up to the next floor once the first floor outer layer may be clearer then get some more kills. This tactic works well for me because i got so many certs from this tactic. To sum it up maybe 2000 over a period of 2 months. This oppurtuinity doesn't show up everyday but maybe every few days.
