Zombie Containment Cells

Zombie Containment Cells are a structure in Plants vs. Zombies: The Cure. It is used to hold zombies and do research on them and the Zombie Virus. A maximum of 7 can be built for a cost of 700 Coins each.

Appearance
Zombie Containment Cells are rows of metallic cages with laser-like blue columns for bars. In the center of the cages there is a computer. At levels levels 3 and above, another cell is added, and on level 2, 2 cells are added. At level 20, the computer becomes gold-plated and larger, and at level 10 the blue columns become red.

Upgrades
The Zombie Containment Cells have two upgradeable statistics: Zombies Held and Research Doable.

Strategy
Leveling up this building to its maximum level is the way to win the game, as the cure cannot be produced any other way.
