Futuremark Games Studio, whose last outing was the well-received by largely unplayed Shattered Horizon, have announced that they are making three new MYSTERY games. They tell us: "you can tag this under PC, XBLA and iOS. We will leave it to your readers to guess which platforms apply to each game (there are only 343 possible combinations)."
Hmm! Let's see whether we can guess from the trailer, which is below. (I think it's actually pretty obvious.)
