Yesterday a new mystery game aimed at a grown-up market was launched, according to CNET news which promises a jackpot of at least $250,000 (£160,000) for whoever solves the case first.

TerraQuest is a game by MindQuest Entertainment and there's a trailer on their website. They say it's due this fall and the news release said it was launched yesterday, but I can't find the actual game online. Not much of an online game then, is it?
