Work is also ongoing on the game’s first expansion pack, to be titled “Island Adventure” and scheduled for release in 2009.
Island Adventure will be the first expansion pack in gaming history that will reduce rather than expand an existing game world. The premise is the crash-landing (without casualties) on a mysterious island in the South Pacific of Hello Kitty Air flight 337, which had been carrying Hello Kitty and friends to the 5th Cuteness World Symposium in Perth, Australia.
Our heroes – including Hello Kitty, Dear Daniel, Keroppi, Badtz-Maru and many others – find themselves marooned on the nameless island along with a couple hundred fellow passengers, whose roles will be filled by end-users. Soon the survivors discover that the island is inhabited by a community of squat, foul-mouthed, inferiorly-animated characters whose only intention is to send the newcomers packing by any means possible.
