Usually, when a company promotes a game, it goes all-out, advertising it with trailers, advertisements and more, in an effort to get gamers excited for it. However, Activision and Square Enix have both hopped on the viral bandwagon for its latest game reveals, both of which tie in to popular game franchises.

Re/Code has reported that Activision’s campaign utilizes small, cryptic clips via Snapchat, with the one first one located here and the second one at this link. Although Call of Duty isn’t mentioned in either one, they do show strange, tranquil visions, where a soothing voice guides the viewer through a number of blurry yet peaceful visions.

The videos can be found via Snapchat codes, which are randomly placed in maps in a previous Call of Duty game, Black Ops II. Once scanned and uploaded, the videos show under the Snapchat QR code name “Snaptags,” which, when scanned, reveals that they came from the “callofduty” account. The video below, produced by YouTube user TmarTn, shows just where these codes can be found.
