Outlast was an oppressive first-person adventure from the Red Barrels studio which tasked players with navigating an awful asylum full of maniacal and grotesque prisoners who wanted nothing more than to show the protagonist his insides. A recent tweet by Red Barrels and a change on their website promises something big is coming tomorrow.

Outlast certainly left a bunch of things up in the air and Red Barrels promised that sequel would come, so this could possibly be leading up to that, though details are extremely vague. Whatever the announcement tomorrow is, it’s sure to come with it’s share of fear and gore, as the Red Barrels website explicitly states “Coming soon… Things are going to get bloody!”
