EXO is gearing up for their comeback and the online traffic is already starting to get jammed.

Currently, the pre-sales of EXO's 4th full album 'The War' with exclusive posters is taking place on Synnara Record. Immediately after the pre-sale became available on July 10, the server shut down due to numerous fans attempting to purchase it.

EXO's 'The War' with the title track ''Ko Ko Bop'' is scheduled to release on July 20. The group's new release is expected to once again create new records in album sales.
