Popcap games and Valve have announced that the Game of the Year edition of Plants Vs Zombies is available now on Steam and on PopCap’s home page.

The GOTY edition feature the full game plus 20 new Steam Achievements, Steam Cloud support, Mac play, and the new Zombatarâ„¢ feature, which lets you create zombie avatars (hence the name).

Plants Vs Zombies is a brilliant little tower defence-style puzzler, with so much depth behind it that you’ll be playing for at least another year to come. It comes strongly recommended, especially with the new stuff included.
