Xbox360Achievements has a list of Achievements for the Xbox Live Arcade version of Popcap’s Plants vs. Zombies, which apparently out multiplayer modes.
The Achievements seemingly give away details of two of the game’s new features, namely co-op and versus modes.
The game hasn’t even been officially announced as yet, although it seems likely to happen on August 2, given a recent tease by the developers.
Plants vs. Zombies sees you try to save your home from waves of undead by using a variety of plants to shoot them down.
The game includes around 50 levels, although chances are there will be even more available in the XBLA version.
It’s currently available on PC, iPhone and iPad. It’s very awesome.
