Namco Bandai Games has announced that the promised Tekken 6 online co-op update is to be released as a free download on January 18 for Xbox 360 and PS3.

Previously playable offline only with an AI companion, Tekken 6's Scenario Campaign mode now let's two players come together online. A co-op leaderboard will be implemented so players can compare their performance with the best in the world.

The update will also include improved Mokujin AI.
