Plants vs. Zombies Web Version is a free version of the game available at the PopCap Games official website. There are three modes: Adventure Mode, Survival and Puzzle. In the Adventure Mode of this version the player can only progress until they finish level 2-4 before they must start again as a new player. However, if one unlocked the Survival and Puzzle modes on one computer previously, they will be able to continue playing those modes. Survival Mode on the web version is a modified version of Survival: Endless which takes place during the night, and the player may only choose four plants at a time. Puzzle Mode consists of a modified version of Vasebreaker. The player's progress will be lost on the Survival and Puzzle modes if they quit, unlike the full version.
