going to try the duplicating zombies with beast mode, thanks for that, will help with all the point farming I do.
here's my tips
1. try to get bowie knife early.
2. use bug and meatball rounds (save one bug) to use a beast mode and get stuff done. easier than one fast zombie following you, or two slow ones.
3. after opening Pack a Punch and killing the Margwa that spawns, get the 3 train symbols, and go back to subway during the same round, use beast mode to: smash statue box, zap three symbols for egg/sword, zap widows wine, mule kick, the door above and stamina-up all in one.
EDIT: using beast mode to zap zombies after hording them up is brilliant. thanks to whoever figured that one out. I had everything but the ww by round 12 by duplicating zombies from round one to round three, only using one beast mode per round though. it makes the first few rounds a little more challenging (having to zap zombies and get things done in beast mode at the same time) but totally worth it. I also tried keeping the gatekeepers alive from when you pick up the items, and leading them to the ritual site to die there, spawning in two more zombies, that works good too.
