After months of hints, rumors and sneaky patches, Valve has officially come forth about the sequel to 2007's critical darling, "Portal." Yes, "Portal 2" is coming before the end of the year and it will (if the above Game Informer cover is any indication) involve going outside.
Details are quite scarce, but thanks to a wacky scavenger hunt in the latest update of the original "Portal," we know that your primary antagonist will be a man named Cave Johnson, the former owner of Aperture Labs who, you may recall, was dead in the original "Portal." Thankfully billionaires are always coming up with new and interesting ways to remain eternal, and I'm willing to bet that Johnson's technical savvy resulted in some sort of AI-driven proxy, who will prove a worthy adversary.
April's Game Informer should be in readers' hands in the near future, and you can bet that it'll involve plenty of additional goo to dissect. Stay tuned.
