What is required:
(I won't say Quick revive, you gotta know that already)
Ray Gun (upgraded)
Scavenger (upgraded)
Matroskha Dolls (optional)
Sickle
Semtex (optional)
Juggernog
PhD Flopper
The lighthouse opened (fully inside)
Stand-in and/or Ensemble Cast done

How it works:

If you acquire all the items (try to around round 15 or so), then here is what you should do.
You should hang out at the bottom of the lighthouse. That way, you could create rape trains (where the zombies pile up and follow you) and they are easily at your mercy. When you get all 23 zombies (that many zombies are allowed on the screen at one time), shoot your upgrade Scavenger into the crowd (NOTE: at round 35, the upgraded Scavenger makes zombies into crawlers, so use two shots) If a zombie tries to corner you in a group of zombies, take out your Ray Gun and shoot at the ground so all the zombies clear up, and continue forward. If George decides to make an entry, lead him to the water where Stamin-up is and fight back in the lighthouse. When you feel that the batch of zombies chasing you is enough to end the round, head to the next paragraph.

If you do that, then this next part will be easier. Create crawlers so you can have time in killing George. After you make your crawlers, lead George to the spawn waters, and unload Hyena Infra-dead shots into him until his light is only orange (no blue glow at all). After this, you knife him with the sickle, backing up when you have taken too many hits. You can also use a few upgraded Ray Gun shots to save more time. After he dies, kill the crawlers first THEN take the Wunderwaffle and perk bottle.


Why is this strategy good?

This is most likely the easiest way to get all seven perks in less than 8 rounds.

The Wunderwaffle EASILY conserves you ammo if used correctly (it kills up to 10 zombies with one shot!).

The Wunderwaffle and Scavenger do NOT make the zombies drop power-ups, meaning there will be more power-ups for you in later rounds (for when you need them most).

By using the upgraded Scavenger the most, you will save ammo in your Ray Gun for when you need it most.

George will be less of a nuisance since he will be constantly dying.

You will not get as bored quickly.

Few more notes:

Quick Revive cannot be re-obtained through the bottle when you fully used up the machine.

Eventually, you will want to have George Romero ride on the rape train around round 35 or higher (yes, he can die out of the water)

Using the Wunderwaffle to get out of a zombie cornering is possible, but don't be surprised if at times you do get down.
