Kingdom Hearts 3 has been in development for what feels like an eternity, and though there have been various teases, trailers and hints dropped over the years, we've somehow yet to see anything substantial about the game. Until now, as yesterday in Santa Monica Square Enix invited us to go hands on with the latest mainline instalment of its bafflingly complex Final Fantasy/Disney mash-up series. There were two playable sections on offer; one short section in the Olympus Coliseum world battling a huge Titan boss, and a much longer, expanded section in Toy Box, the Toy Story themed world. The demo in Olympus Coliseum heavily featured the new wall-scaling autorun mechanic, with Sora, Goofy and Donald scaling sheer cliff faces as the Titan pelted rocks at them from above, and culminated in a boss battle with the Titan on the summit, with Sora summoning the Big Magic Mountain attraction to finish it off, which looked pretty incredible. There were some camera issues as the framing struggled to keep up with Sora in confined stretches of the cliff face and when it was vying for space with the Titan at the top of the mountain, but it was a fun showcase of the new features in KH3's combat, including key blade transformations and the bombastic attractions.
