SPOILER ALERT! This isn't a joke...

What do you get if you cross one of my all-time favourite turn-based trajectory games with my third favourite sport?

Worms Crazy Golf on iPhone, that's what.

UK-based developers Team17 are, of course, the brains behind the long-running Worms series, and they recently announced that their famous band of garden invertebrates will be putting for glory later this year.

Players will have to execute skilful chip shots and precision putts across three madcap 18-hole courses, while overcoming obstacles like castles that teleport balls and comedy bats.

Old, familiar faces from the Worms universe will make an appearance in Worms Crazy Golf, including the sheep, old woman, and mole.

Team17's Head of Design John Dennis has this to say about his studio's upcoming game:

We've had a great deal of fun playing the game in multiplayer during development, and with four-player social multiplayer support, it has all the hallmarks of the 'Worms' brand: the trash-talking, pressure to make the shot, terribly unhelpful 'advice' from opponents, and often hilarious consequences when that risky shot that could have won the game goes terribly wrong.

Worms Crazy Golf will pitch up on the App Store green later in 2011.
