    On the Finale do not restart the generator and a wave of zombies keep coming.

    It will probably take 1-2hours to get the 5k kills using this method less if u have played thru the campaign already as u will have some kills done.

    DarthDawaHit or miss for me on the special infected. Sometimes they spawn after the second tank is dead and sometimes they don't. I'm on my second try now for progress toward the "zombie genocidest', got 'the littlest genocide' the first time it worked in about an out starting with 1300 kills. Just don't kills your AI until after a few waves to be sure there are no special infected. Even so, leave one alive and eventually the horde will take him out.

    KillaKevin24Well I am working on this currently and I killed an AI off after every wave to make sure of the special infected. Once I killed the last AI no more special infected spawned and I am sitting in the corner by the light and meleeing everything. So it really is hit or miss with the special infected.

    I managed to get this achievements same way i got the original genocidest, when in the saferoom at the start of the finale, on expert kill all bots and you can either do the next bit on easy or expert. Expert may make it quicker, not to sure. But try get the attention of a boomer by going in and out of the safe room and outside a few times, i usually got one when the first horde comes. when You have one just use an elastic band and just do the LT button, against the door with the boomer puking on you.
    The boomer sometimes walks away or stands in the corner and doesnt puke on you, but keep trying to get it right and you will.

    Good Luck :)

    Shadow XBLahh I see. Well the same solution as the larger genocide one works for this one - just run it all night. Even without opening it you'll eventually get it.

    eHeadachesyeah takes a while to get it going but it works for sure, i tried with the boomer in the safe room and he played for a little bit but then started clawing at me after a while. They sure are ugly bastards.

    GREGO McGEEAny way to keep the Boomer from detonating himself. Happens every time when he charges the door.

    A really easy to get this is to play a Versus game with two controllers on the Finale chapter of Crash Course. Set your main profile as the survivors and the other as the infected.

    Simply make your way to the end of the level to the generator and climb up the generator pole. Infected should not be able to reach you up there. Killing all AI helps as well as you can get more kills. So start the generator, climb the pole, and fire away. It's best to use dual pistols. Do not restart the generator after it turns off and the horde will keep coming.

    As you're on Versus you won't have to worry about the Special Infected as they'll be idle on the other controller. However, make sure it's always a Boomer as when it becomes the Tank, the AI will take over whatever the controller had.

    I got about 300 kills in 5 minutes using this method.

    A good tip is to use the other controller as a Boomer and vomit on the Survivor every now and then so even more zombies appear.

    Shemp HowardThis is the way I got my achievement. There was a video up that was not very good, but it kind of showed the action. I may make a video and give you the link so you can use it. Just don't know if I have the time to do one anytime soon. This is the best way to get this achievement, and these also go toward the 53k kill achievement as well.

    Yeah, there used to a be video on here but it went when TA went down. Couldn't find it again afterwards either. But like you said, it wasn't great. It just showed someone on top of the generator pole; not actually how to do it. So I'd be extremely grateful if you were to make a video to add to this solution. Cheers :)
