The Playforge's undead-filled agricultural offering Zombie Farm has been updated with a host of social features and daily bonuses.
An entirely new social menu now allows you to invite your buddies to the game through Facebook, email, and username, to visit their farms, and to send them gifts.
Mini-games such as Zombie Tag - which gifts you XP if you can catch all of your friend's brain munchers - are also available.
Last but not least, you can play a new daily bonus mini-game called 'Wheel of Brains', which invites you to win gold and brains (the game's premium currency) each day.
Like FarmVille, your job in Zombie Farm is to plow soil, plant crops, and harvest them for profit. You can also, however, grow your own legion of walking corpses.
Once 'harvested', you can send your army on invasions to nearby farms and cities in the hope of earning rewards.
Zombie Farm is free to download for both the iPhone and iPad, but you can buy extra items with real cash through in-app purchases.
It's one of the 20 games compatible with DeNA's social gaming platform Mobage, which graced Android phones around the world yesterday, and it's one of our top 10 best iPhone farming sims.
