The UK Government is planning a coordinated push north of the Border to get across the message that cheaper mortgages, safer banks and more jobs will be at risk under independence.
Ministers will visit different Scottish cities talking about Scotland's strong economic performance as part of the UK and the valuable contribution being made to the UK's economic recovery.
The Government is promising to publish detailed analysis of the UK and Scotland's relatively strong economic performance, which they will claim undermines the belief that being part of Britain holds Scotland back.
A UK Government spokesman said: "Cheaper mortgages, safer banks and more jobs are all part of the evidence that we have laid out for the Scottish people."
A spokesman for the Deputy First Minister Nicola Sturgeon said: "It was the No Campaign itself that described its own campaign as 'Project Fear'.
"This fig leaf of a 'positive' campaign is a clear sign that they know how deeply damaging that revelation was.
But people won't be fooled - everything about the No campaign is negative and designed to talk Scotland down."
