PvZ : Battle for Neighborville introduced a few new mechanics, one of which is "overhealth".
The achievement can be unlocked in about 10 minutes or less.
- spawn in the game
- find a changing station and switch to scientist
- start running after random players in your starting area
- press
when close to them and stay close to them for 3-4 seconds.
You'll see numbers pop on the player ( extra health ) and his red bar filling over with a yellow bar, once it has stopped filling ( roughly at third of the bar ), switch to the next player, and so on.
