How to get unlimted xp

Step1. Make a private story mode match(or public) and select the scence as ambush.

Step2. Reach the checkpoint where you see to people garding the bomb..

Step3. Chuck a gernade You should get 2 kills run to the bomb and press X/A

Step4. Once your guy is coming to defuse it once he sits down you throw a frag gernade right by the door then look at the turret

Step5. Now he will just keep spawning..


NOTE: i did this for about 7-8 hours and turned from a warant officer to a elite

Now ive been heraing that it gets laggy and after a while when im doing it he defuses the bomb also ive been hearing if i make and the game finishes and i accedintly win the mission what do i do well your qestions are going to be answered today >>>

HOW TO- 1. if your game gets laggy.. make sure ur thermal isnt on.2 make sure that if your the second person in the game you will get booted and lose all your rank..

HOW TO-2 When you r relloding dont runn away becuase ur person defuses the bomb if there is no shooting going on.

HOW TO-3 If you accedently finish the mission press start and go last checkpoint or something

I finally got this but you don't need to make a match online you can go into single player by yourself and do this. Also when people are saying several guys swarm in when he is defusing the bomb that is true!! I found out that if you stand in a certain spot nobody will come in the room and you can keep killing the guy that re-spawns and goes to the gun but when I moved to another area all the guys came rushing in and I died.

that a long time

7-8 hours, you wouldnt get to elite think about ammo, people killing you and warrant officer is at like 200000 points elites 400000 you would need so many kills

If you concentrate enough and be very patient you can get like 20000xp every 20 mins. And then when you run out of ammo reload the checkpoint. But I don't think many people would sit there for 7-8 hours doing something sooo boring.

Me and my friend only did this for 30 mins because it is very boring. What we did is when one person needed to reload the other went and when he needed to reload I went and so on.

I just leave my xbox on and let the dumbass AI team mate do it, it's slower but it's good for when you're not able to play.

yahh play a lil than tape ur controller l button take cover somwhere and leave it on go to sleep and u mite wake up 1 or 2 ranks

Here is 3 good tips. #1 aftrer you kill the two guys walk far away from the bomb and then tell your team mates to hold still. then walk back and do the glitch when the guy spawns wait like 15 or 2o seconds you should beable to tell your team mate to stay before they come to arm the bomb. It make it alot eaiser so you dont have to reload the map when they die. #2 when you out of ammo you can always just walk back to the begining and get more. #3 When you start lagging walk into the red room. You should stop lagging

O yea and you dont have to throw a frag at the door you can put a c4 on any of the window things next to the door. Then press A then press B to blow th c4

If you need any help send me a friend request on xbl Oo ShOt Up oO

I just tried this.And it does work but mins goes really laggy and when i get rid of the lag the bomb has been defused and its th end of the mission.....
What should i do to stay at that bit but without the laggines...

Walk into the red room when it get really laggy. When i have to reload i walk into the room then go back to doing it
