How to unlock the ZFF's 4 Evr achievement in Plants vs. Zombies - Definitive Guide
The achievement should pop for both player 1 and player 2. I'm unsure if you need to have completed adventure mode first.
In terms of winning at bowling I'd recommend saving the red walnuts for larger groups and don't be afraid to let the lawnmowers take out a row or two especially towards the end. I hope this helps!
I did this by myself with two controllers first try, but it was stressful. You also have to be quick about it, if you're doing it alone. So half the time I was alternating between controllers very fast and setting them down on the ground. The other half of the time, I was using one hand for each controller. If you have a buddy, it's super easy to do it the way it was meant to be played. But if you don't, don't sweat! You can knock it out in 10 minutes if you're focused.
Here's a vid:
Once you complete adventure mode you will need to go play the Wall-Nut bowling mini game. After you complete this in the coop mode Wall-Nut bowling will become available. Just play through it with a friend or have the 2nd controller as a back up to store Wall-Nuts so you can switch over when you run out. Remember to bowl the Wall-Nut which kills the last zombie.
Once you have finished Adventure Mode Wall-Nut Bowling will become available in Co-op Mode. Bowling a "winner" means winning the round. To bowl a Wall-Nut press to send the Wall-nut down the row you placed it on. Simply play through the Wall-Nut Bowling with two controllers ensuring that you use the first controller to kill the last zombie.
PLEASE NOTE: Some people have reported needing to complete the bowling mini game in solo, before it will show up in co-op. So, if you finish your adventure mode playthrough and do not have the co-op bowling available, simply complete the solo bowling first.
