Part of this teaser you're about to watch is live-action. Other parts are generated by an all-new bleeding-edge graphics engine. And, even if you can tell what's been recorded in reality and what's generated by software, you have to admit that the border between the two looks like it's dissolving.
The clip is for Get Even, a single/multiplayer hybrid shooter being developed by The Farm 51.
Get Even subtlety removes the classic division between single-player and multiplayer experiences to unfold two linked stories. The game's plot revolves around the memories of its central heroes which have a dramatic effect on how the game progresses.
It uses an environmental scanning technology called Thorskan, created by special effects house Better Reality. The trailer doesn't have any examples of gameplay or story set-up. Mostly, it's showing off how good the creators can make stuff look. Don't expect to see Get Even before 2015.
