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" possibly means "zombie friends forever." The phrase "ZFF" can also mean "zombie fighting friends," due to there being two Sunflowers. However, this is less likely. The way this achievement is misspelled could be a reference to how the zombies would often misspell words on their notes.
