This afternoon, PopCap Games updated their Steam version of Plants vs. Zombies with twelve achievements. The Steam Achievements aren’t exactly easy to obtain -- many will require deep concentration (reach 20 flags in Survival Endless) and the dismissal of all things social (re: Grow the Tree of Wisdom to 100 feet.)

Here’s the full list:

Home Lawn Security: Complete adventure mode.
Morticulturalist: Collect all 49 plants.
Towering Wisdom: Grow the Tree of Wisdom to 100 feet.
Nobel Peas Prize: Get the golden sunflower trophy.
Better Off Dead: Get to a streak of 10 in I,Zombie Endless.
China Shop: Get to a streak of 15 in Vasebreaker Endless.
Immortal: Get to 20 flags in Survival Endless.
Cryptozombologist: Discover the top secret zombie.
Walk This Way: Hypnotize the lead dancer zombie.
Spudow!: Blow up a zombie using a potato mine.
Explodonator: Blow up 10 zombies with a single cherry bomb.
Ask Me About Mustache Mode: Enable Mustache Mode.

Unfortunately, I believe I've only earned one of these Achievements. How many have you guys unlocked?
