Brink

Annoying but very fast and easy way to boost :

Have a light class to run faster.
Make the soldier class your default class.

Select free play, private game, objective type, invitation only
Map : Labs
Customize server :
Min Team Size : 0
Max team size : 1
Players needed : 1

Start as Resistance.

Notice that you're alone with no ennemies, but you'll still get the xp.

Then just rush the primary objectives.
Rush to the door, plant the bomb and stay close to it until it explodes.
Then rush to the post in front of you and take Ingineer class, rush to the Bio-sequencer and repair it (longest part). When done, the sample will drop in front of it, just take it to the submarine.

Don't forget to hold LB to sprint.

When you'll know well the path, it'll take you 3 minutes to make it all. Thanks to the bonus, you'll get 5500 xp in 4 minutes including the loadings. (About 83 000 xp an hour)

OK. Firstly this will get you just under 100,000 XP in one go !!! With absolutely minimal effort required.

Note: This can do done with a bot OR another player

Firstly, props to KamiKazeKore and Tatakai no Kami. this is a modification of their strategys

So setup the game in the following manner:

Freeplay - Private Match - Versus - Only Invation (+20%)
Map: Reactor
Min Player: 0
Max Player: 1
Overtime: Yes

Player that needs most XP as Resistance, other players as Security

Resistance: Operative
Security: Engineer

Both go to the same vent

Resistance player starts hacking

Security waits until percentage is at 20% then simultaneously starts to remove hackbox (they will have to hold the X button down to accomplish this, perhaps some sticky tape ?)

IMPORTANT: Both players are hacking AND removing at the same time so BOTH players get XP at the same time

Now, in this setup, you will notice that the hack percentage still goes up. In order to combat this, the Resistance player that is hacking simply needs to move further back so that the hack is less effective

Back by how much ? Well the easy bit is to move back until the hack percentage counter in the top right of the screen turns from yellow to orange. Once it has done this move EVER so slightly forward until it goes back to yellow, no more

Once you have this setup, the percentage will no move, the timer will run to 0 and then overtime will continue, there is NO end game in this situation (I've had it up to 1h34m like this)

No further effort is required AT ALL until the game ends (unbelieveable I know)

CAUTION: The XP counter will RESET once it gets to 99,999 XP. Therefore you MUST stop the game at approx 90,000 XP in order to allow for the end game bonus (yes I found out the hard way, lost over 100k in XP :( )

Remember, the security player will get MORE XP than resistance, but considering you can get approx 80-90k EACH in one go without any effort, easy to repeat

Best of luck

I did this by mistake, I was still going to the reactor and hiding for about 27-30,000 after 30 minutes............. that's the wrong way to boost.

You need to make an objective game and make it friends and invite only.
Min players1
Max players1
Map reactor
Overtime On
Switch teams to Resistance if you don't start as that team
Select an Operative Class

I always went after the right vent(probably can go left if you want) and it works much better with a character lower tier 2 or under.(level 13 and down)

What you do is you run in and hack the vent, when the AI comes (usually from the top middle the first time) you kill him.

If you stand right behind the hack box with the vent blocking your view from the door, the AI will always come in the room from that side and start to defuse if he doesn't see you. He will lock into the defuse even if he sees you after he starts (happens at level 20 too but the AI can stop defusing after a 1 minute or so if he is looking right at you). kill him and start hacking again.

Do this until the hacker hits 70-75%. After that you continue to hide on the left side of the vent right next to the hack box but about 3 steps back, with your characters body completely hiding from the site of the bot but don't kill him when he locks in.

Again seeing no enemy, the bot will run up to the vent and hack. Even if he sees you after starting he won't stop hacking (at lower levels), but to be safe you should hide to the opposite side of where the bot comes to defuse at. If he is to the left, you're to the right of the vent. And if he is in the middle just hide straight behind the Vent. Basically keep the vent between the you and the AI.

Now this is the important part, you start to back away from the Hacking vent until the percentage in the right goes from yellow to orange/brown. This means the AI is defusing more than you are hacking. It happens around 4 bars of connection or when you see your hack points are at +12 or +13.(At higher levels the AI could have engineer skills that let him defuse faster, so tier 3 players might have to sit closer)

Once you are in a sweet spot of inching forward and backwards in this range, make sure you leave it just in the orange/brown range. This will likely freeze the counter or worse case it will take the bot hours to defuse from 95%. After that you just walk away, go to sleep, change your car oil......what ever.

Because if you get this right the game will go into Overtime and keep going, after 120 minutes you should have about 170,000 exp if you stop hacking and let the bot defuse. Never Quit.

These are all projections because I was done with the game after 1 hour.

If you left for 2 hours it you should have 240,000 and a 15% bonus 3600.
3 hours would be 360,000 bonus 54,000.
4 hours would be 480,000 bonus 72,000.
So in 3 1/2 to 4 hours, you can go from level 1 to 24.

Sidenote: for level 13 and higher tier 3 plus players, the computer will be more aggressive because he has more skill/skills. The engineer will be much more likely to stop his hack to look for you if you are too close or to put down a turret or mine.

Level 20 players should check after 30 minutes to a hour to see if they are dead on the ground. You can get it to where he will leave you alone depending on the AI they set for that match, but things can go wrong with the super aggressive Bot.

He usually has the ability to shoot after you down him. Watch out for that bot if you are level 20 or higher.

*******Update:To avoid the aggressive Bot- " Start up Brink offline. This disables the DLC which is important. I can verify from testing that the so-called "smart" or aggressive AI only appears when the DLC is active. In the menus, now sign back into XBL and set up the vs. match, but this is the great part - the DLC will remain disabled."

The Level caps at 20 and exp at 300,00 but it saves all exp earned and it will unlock the next time you log in to the DLC

Quick video showing easiest XP boost method - You need just over 500k XP - In the video i get 163k in just over an hour - If you like the video check out youtube - Needtoachieve

For this you need 2 people to make it work, Pick the map reactor in a custom game, have one person go resistance and one security. For the resistance, that player needs to go operative and plant a hack box. For security, that player needs to go engineer to remove the box. The goal here is to both be hacking and removing the box at the same time. The operative should stop at around 98% and let the engineer reduce the hack, once its in around 5% the operative can continue hacking. With this both players can easily earn around 40k+ per game.

Well, there is a very easy, if not incredibly boring way to do this. First, pick the map Reactor, then choose to be Resistance. Set it so there are 2 bots on your team and 3 on the other. Then, start the match. As soon as it starts, run as fast as you can to the objective on the left. Now, go stand behind the pillar right behind the hacking objective. There, you will get points for defending, and for some reason, the enemies will rarely see you. I averaged 24,000 points a match doing this. Very easy and fast way to rank up.
