Sony PlayStation is letting players create their own trailer for its Killzone Shadow Fall, including their own gameplay footage, with an app designed to highlight PS4's new Share Function.

The app, which can be accessed on the game's accompanying website, was created by production company The Famous Group in collaboration with BBH New York (the agency behind the official launch spot). It allows gamers to upload and remix gameplay footage to create a personalized custom trailer after logging into the site through Facebook.

Gamers can include their own most epic moments of gameplay, and once they've pulled in their choices, use a drag-and-drop video editing tool to remix the content and submit the trailer for consideration. After a moderation step, users get a Facebook notice if their custom trailer is accepted, at which point they can share the trailer with friends and the gaming community on Facebook and Twitter. It's all designed at plugging the Share button on PS4, which lets users share their gameplay via social media.
