US retailer mag Game Informer has started teasing its next issue, which is said to feature a new game that "old school gamers will freak out over."
The mysterious title, which is set for reveal this Thursday, January 5, is said to be a new instalment in an established series, but "the real nuts" of the surprise is apparently its developer.
Executive editor Andrew Reiner tweeted: "Our next cover is another 'what the?' type of reveal. I suspect old school gamers will freak out over this one."
The reveal's anyone's guess at the moment, though Game Informer has since said the title in question is not a first-person shooter. That rules out Half-Life 3 by Lionhead, then.
