French multinational media conglomerate, Vivendi, has made another move on Assassin's Creed creator, Ubisoft.

According to a report by Reuters, a letter to French stock market regulator, the AMF, shows Vivendi now holds 17.73 percent of Ubisoft's company value, along with a 15.66 percent share of its voting rights.

Despite its continued advances -- which Ubisoft CEO, Yves Guillemot, last year branded "unsolicited and unwelcome," -- Vivendi says it has no immediate plans to seek control of Ubisoft, or table a public offer for any outstanding shares.

Vivendi's interest in Ubisoft began late last year, when it purchased a 10.39 percent stake in the developer for 244 million euros.

At the same time Vivendi also began buying up shares in French mobile studio, Gameloft, eventually snapping up 30 percent of the company's stock to force a mandatory takeover bid.
