With the game sadly not explaining how to do this, there's a strong chance you'll do the same as we did, and load up your existing save game, before searching your existing kingdom for any signs of aliens.

Once you've downloaded the add-on, you'll have to boot up A World of Keflings, and start a brand new game, choosing to play 'It Came From Outer Space' from there. Seemingly, when it comes to 'It Came From Outer Space', the first challenge is actually working out how to run it. We bet it was that meddling witch's fault the add-on took so long coming. Rejoicing, and polishing off our hats, 'It Came From Outer Space' appeared on the Xbox Live Marketplace for 320 Microsoft Points (about £2.67, depending on where you bought your points) some ten months after the game's release, and we downloaded it almost straight away. NinjaBee had hinted at the possibilities of downloadable expansions, but that was many moons ago, and we'd pretty much given up all hope - until, out of the blue, 'It Came From Outer Space' was announced. Then, after what seemed like an eternity, the sequel, 'A World Of Keflings' emerged in 2010, and we played that to death too, this time with a spruced up storyline, and buckets of humour - but once it was finished, we were a bit sad.

Making you a giant amongst a race of tiny people with massive chins and a penchant for hats, you helped the Keflings build the kingdom of their dreams by setting them to work mining rocks, chopping down trees, and processing the raw materials into beautiful bricks, in order to put together the buildings that made up their world. Way back in 2008 NinjaBee brought their original kingdom-building simulation game, 'A Kingdom For Keflings' to the Xbox Live Arcade, and we played it to death.
