EDIT: Turns out the trailer is fan-made, and not official in any way. Which is kind of a shame, because it’s awesome.
The new Alice game, which will be called Return Of American McGee’s Alice, is miles off, being set for release in 2011. It is being developed by Shanghai studio, Spicy Horse. There’s not much more to go on at present, other than the teaser site, and a brilliantly creepy teaser trailer, posted below.
