The Playforge's undead-packed freemium hit Zombie Farm has been treated to a small update, which adds two brand-new invasions for you to undertake.
Your home-grown army of flesh eaters can now visit the circus and teach its inhabitants to “stop clowin' around”, before attempting to save Halloween from the evil Count von Uberiss.
You can, of course, still take part in the game's classic invasions, which see you battle it out with pirates, ninjas, aliens, robots, farmers, and lawyers – the most evilest opponent of them all.
Gameplay aside, the new update introduces a news wall that will keep you in the loop about the game's latest events, and also includes a casket full of bug fixes.
You can shuffle over to the App Store and pick-up Zombie Farm without spending a penny.
