Konami has announced that the latest downloadable content for Metal Gear Online will be released on November 25th. Entitled Meme Expansion, the download adds new characters and gameplay elements to Hideo Kojima’s hugely popular online epic.

The Meme Expansion unveils two new special characters, which are playable for the first time. Liquid Ocelot enters the fray with the ability to manipulate the Sons of the Patriots’ lock system using his Guns of the Patriots skills, and Mei Ling comes into play with three unique attributes, including the Trench Mortar weapon, Soliton Sonar capabilities, and the means to transfix enemies.

Three new maps have also been created, with the rough, uneven industrial elements of Silo Sunset, the dense foliage of Forest Firefight and a snow-blown deserted factory called Winter Warehouse available for the first time.

The download also implements a number of new rules, which are also now available without the Meme Expansion update. A new ‘No Headshot’ setting allows players to attribute the same level of damage when shot in the head to that of a regular body shot. ‘Stealth Death Match’ allows users to compete with the stealth elements switched on automatically; while the ‘Interval’ setting allows used to practice and chat with each other within the battlefield, without their ranking or records being adversely affected.
