ZFF's 4 Evr is an achievement that can be unlocked on the Xbox 360 and PlayStation Network versions of Plants vs. Zombies. In order to unlock it, the player must win a game of Co-op Bowling. This can only be achieved when two players are active. Wall-nut Bowling will be harder this time around with Gargantuars (and Imps, of course), Zombonis and Zombie Bobsled Teams coming in, alongside no aid of Giant Wall-nut. However, there will be no Dancing Zombies and Newspaper Zombies and the player's friend can help them. If both players win, they both get the achievement.
"ZFF" is a reference to the phrase "BFF," which means "best friends forever." So "ZFF" means "zombie friends forever."
