Namco Bandai has released this trailer for Inversion. It's a live-action thing, so I guess its purpose is to remind us that there will be gravity-manipulation in the game. The bit with the ketchup packet amused me. Mission accomplished.
Hamza previewed the game back in February and seemed to think that the title had potential but needed work. With a release date set for early 2012, they have a fair bit of time yet.
