Knock-Knock was released yesterday and a new gameplay trailer made available.

Knock-Knock is a horror themed adventure game developed and published by Russian studio: Ice-Pick Lodge. The game is based around 19 files containing snippets of text, audio recording and fragments of video footage sent to the developers by an anonymous emailer. They were asked to finish the project using the information stores in the files and that they must use everything but have complete creative freedom otherwise.

The game is essentially hide and seek, but against usual guests who are visiting the house of a shut-in. You play as the Lodger who has noticed weird changes, things are missing, noises and rattling is heard and something seems to come out the woods. You must stay awake and sane until dawn.
