• Changes to the Second Chance Perk – if you put a player into Second Chance and he isn’t revived then you will be credited with the kill. Anyone else who finishes them off will now only get an assist.
• Tweaking of the AK74u to make it more balanced.
• Various fixes for bugs and freezes. 

For a full list of changes check out the official update thread over on the COD HQ forums.  Make sure you exit the game completely at 10am and then load it up again to get the patch.
I will post my thoughts on Patch 1.06 later after I have been able to thoroughly test it.  I’m really looking forward to seeing the changes to Second Chance in action as that perk has been one of the biggest gameplay frustrations for gamers.  It should make the system fairer and more balanced.  I for one end up getting a lot of assists instead of kills because of it.  It will also be interesting to see if Patch 1.06 brings greater stability as I’ve noticed (along with the people I game with) a sharp increase in connectivity and other errors recently.
In the meantime please discuss your own experiences of the patch either using the comments section below or over at the official Tsardom.net Fan Page on Facebook where you can also support the site by becoming a fan.  You can find more content about the game, including in depth feature reviews, gameplay videos and details of the upcoming First Strike DLC, at the Call of Duty: Black Ops section of Tsardom.net.
