Presumably filmed at QuakeCon, the video shows off some gunplay and a crowd-pleasing chainsaw beheading.
Powered by id Tech 5 and set for release in 2014 on PS3, Xbox 360, PS4, Xbox One and PC, The Evil Within is the latest game from Resident Evil creator Shinji Mikami.
Earlier this year, he explained his return to the survival horror genre by saying: "Survival horror as a genre is becoming all action now and there aren't any real survival horror games in the world right now. That is the biggest motivation for me."
In our first The Evil Within preview, we said: "The Evil Within is a welcome return to survival horror. It mixes the over-the-shoulder combat (and chainsaw-wielding nutters) of Resident Evil 4 with the grim, psychological horror of Silent Hill, and the id Tech-powered visuals are beautifully atmospheric."
