Ubisoft have announced that the first weekly free DLC for Splinter Cell: Conviction hits Xbox Live today in North America (Europe is still waiting for the game to release). Today's download is a MP7A1 Machine Pistol, and more free stuff including a Deniable Ops map, weapons and skins to look forward to.
It is unknown whether the same free DLC plan will include Europe, but we expect it to be something similar.
