An "Exodus" from one of SM Entertainment's most popular idol groups will be revealed on March 30.

SM Entertainment began releasing teaser images entitled "Pathcode" for EXO's 2015 comeback. The first video, released on March 18, featured EXO member Kai and the follow up video on March 19 featured fellow member Tao. Along with the videos, an official Twitter account was set up to offer hints for fans to view teaser pictures on EXO's official website.

The K-Pop Herald reported that EXO will make its comeback on March 30 with the album "Exodus."

The two teaser videos, titled "Pathcode #KAI" and "Pathcode #TAO" respectively featured each member of the SM Entertainment idol group in different countries. Kai appeared in London, while Tao appeared in Barcelona.

Both members exhibited the faux-powers that the idol group debuted with in their original teaser videos, where the twelve debut members of EXO had their own powers.

EXO's debut music videos and teasers in 2012 positioned the twelve members as supernatural beings from an exoplanet.

The idol group's official website was updated daily with a new member's teaser images, along with an answer box for fans to answer. Fans discovered the twitter account PathcodeEXO, which has offered hints to solve the question as each member's teaser video was uploaded.

The order of teaser videos follow the original teaser release order from 2012, and "Exodus" is being represented as EXO's re-debut. SM Entertainment originally released EXO's individual and group debut videos beginning with Kai. It is expected that the "Exodus" teaser videos follow the same release order, with EXO Sehun's teaser being released on March 19.  Kai's first teaser was followed by teaser appearances of Luhan, Tao, Sehun, Lay, Ciumin, D.O, Suho, Kris, Chen, Baekhyun, and, finally, Chanyeol.

In 2014, two members, Kris (Wu Yi Fan) and Luhan, exited the idol group. 'Exodus' will be the group's first album with ten members.
