A list of Achievements for the XBLA version of PopCap’s zombie-tower-defense-gardening game Plants vs. Zombies reveals some type of Co-Op and versus modes. The full list, which can be looked over at xbox360achievements.org, offers fans and newcomers alike a glimpse at what the requirements are and the sense of humor within the game.

However, other than the Achievement description, there’s no other indication to what the versus and co-0p modes might actually be like, but at least there is some confirmation that they’re in the game.
