I did this when getting to round 30 its very recommended and very effective.
1.To do this you need to shoot george.
2.Get him close to flinger.
3.Let him get close.
4.Shoot him with VR-11 to calm him down
5.Shoot him to get him mad, while he is raging quickly shoot him again.
6.Take the flinger.
7.Dont shoot or knife george or he will unfreeze
^^^^^^^^^^^^^^
Yes this works for PS3
To do these laps you need.
1. A Good Team mate
2. Be Good At Getting out of choke points
Recomended.
1. Raygun (To get through choke points)
2. HK21 or RPK (For Points)
3. Jugg (To not die)
4. Flopper (To use your raygun if you get trapped and not die)
5. Stamina (Run through choke points)
6. Quick Revive (If your team mate goes down on high rounds, most likely you will not be getting him without dying.)
Tips:
Don't try to kill george (Waste of ammo)
Don't try to hold down a spot longer than you need to (You will pay for it)
Keep moving if team mate goes down (You dont need to be a hero)
Open doors! (Don't be an asshole, most likely you will get your points back by round 15 so don't cry about loosing 1000)
i just freeze george and play with people who can handle themselves . it works too. went 38 rounds last night with 2/4 people. just find a place where you are comfortable and run big circles.
Also, once you get enough points (about 20-30k), you don't really need a point-whore-ish gun, so you can swap out your MG for something like the scavenger. Also, if you have about 10-15 minutes to **** around, you can kill George by rapid knifing with the sickle (took me and my brother about 10-15 on round 23). It wastes no ammo and you get an extra perk and death machine/Wunderwaffe
