If, like me, you adore survival horror games, you've probably has your eye on Knock-Knock for some time.

Well, prepare to have that eye filled with flickering lightbulbs, filthy walls, and other creepy imagery, courtesy of the game's brand new trailer.

If you're unfamiliar with Knock-Knock, it follows the exploits of an insomniac wandering around his house being harrased by malevolent spirits.

Partially funded via Kickstarter, the game popped up on our rader because of its fantastic art and animation. Some of the beasties look pretty unsettling, too.

Plus, as it seems you only have a candle for protection, there's a chance we might actually feel under theat when trying to escape the ghosts and ghoulies.

You know - like in a horror game.

You can check out the new Knock-Knock trailer above. There's no set release date yet, but we've been assured by the developer that it's coming "very soon."
