Metal Slug XX Online was a run 'n gun title released in 2017 for iOS and Android compatible devices, developed by CocoBear under license from SNK. Initially released in Arabic, it included all playable characters present in Metal Slug XX, along with a newcomer - Amir. A later global release swapped Amir out for Nadia in other regions.
As all game servers have since closed, XX Online is no longer playable.
The game offered classic run and gun game play adapted to the touch controls, as well as high definition sprites. The hundred levels were short, straightforward affairs, in keeping with XX Online's casual nature.
The Arabic release featured various special events during important Middle-Eastern holidays, such as Ramadan.
