Plants vs. Zombies: Showdown/Upgrades

''Upgrades are stuff in Plants vs. Zombies: Showdown that can level up your plant or zombie. There are different kinds of upgrades. The main 3 are In-game, character, and stat. In-game just levels up your stats, but erases all kinds of level-up you've done when you finish the level unless you're playing Survival or Chaos mode. You pay for it with Powerberry points. Character lets you unlock new missions and attacks and levels up your sun cost and recharge. This happens after you use the leveled up plant for long enough. Stat is where you level up certain stats of an attack any way you want. You pay for it with XP.''
