Ok here is the easiest way to kill George hands down. I did it by round 5 some people say it can be done around round 4. Here's what you want to do:

1)Start the game, right when it starts if you don't see the glowing mystery box right in front of you up by the light tower, KEEP RESTARTING UNTIL IT IS THERE.

2)There is a reason you want the box there. If it starts there you only have to pay 750 points to get to it and start using it right away, can even be reached before the end of round 1

3)Once you start and the box is there, for the first two levels just knife and rack up as much points as possible

4)On round 3 start using your pistol fire 6 shots at each zombie then knife for more points, by now you should have a decent amount

5)Go up to the box and use it hopefully you'll get a wonderweapon or something good, you will beat him with any of these guns: LMG'S, SPAZ, RAYGUN. If you don't get any of these you can use weaker guns but it'll take longer

6)The whole battle is going to take place right in the beginning, keep rack up points and at the end of round 4 MAKE SURE YOU HAVE A CRAWLER I CAN'T STRESS THAT ENOUGH

7)Now get george and your crawler near one another and shoot george to piss him off. Make sure he swings his hammer down at you and the crawler but don't die, after this run into the water to cool him off.

8)Now you have an electric crawler that will NEVER DIE UNLESS YOU ALLOW HIM TO TOUCH THE WATER

9)So the rest of the fight is going to go like this you are gonna UNLOAD everything you got on george (try to do it only when he is in the water, if you hit him outta the water run back in to cool him off). While all this is going on YOU MUST KEEP TRACK OF YOUR CRAWLER cuz if it touches the water, round over and more zombies will begin to attack

10)The battle is mainly going to consist of you trying to keep george in the water and your crawler out of the water, may seem complicated but it really isn't. If by the end of round 4 he is still alive kill the crawler, go through round 5 rackin up more points for weapons on george, at the end of round 5 do the electric crawler thing again

YOU WILL KNOW WHEN GEORGE IS DYING BECAUSE THE LIGHT HE IS CARRYING WILL START TO FLICKER. IT WILL ALSO TURN FROM A SHADE OF LIGHT BLUE TO ORANGE, THEN EVENTUALLY IT WILL EXPLODE. AND BAM YOU'VE KILLED GEORGE SOLO!!!!

Please Thank and + REP if this helped!!!

EDIT: AFTER YOU KILL HIM YOU WILL RECEIVE A DEATH MACHINE AND AN ACHIEVEMENT. DON'T THINK HE'S GONE FOREVER THOUGH IF YOU CONTINUE TO PLAY HE WILL COME BACK A COUPLE ROUNDS LATER!!!

ALSO IF YOU USE THE RESTART STRATEGY TIL THE BOX APPEARS IN FRONT OF YOU BY THE LIGHTHOUSE AND CAN GET TO IT WITH A MEASELY 750 POINTS YOU CAN ALSO GET THE "STUNTMAN" and "SHOOTING ON LOCATION" ACHIEVEMENTS. Just keep restartin til you get the box and get one of the two weapons, go turn the power on so you can pap whichever one you get and use it!!
