Widnes have snapped up utility back Gary Hulse from Warrington on a one-year deal, to become the fifth new face to join the club.
The Vikings have already signed Terry O'Connor, Mick Cassidy, John Stankevitch and Misili Manu.
Fans at the Halton Stadium were also further boosted on Saturday by the news that Wales prop David Mills has re-signed for the club.
"I now feel that Widnes are really going places," said Hulse.
"They are showing a lot of ambition and I am glad to be part of it.
"I thought it was the right time in my career to move and develop and I hope I can bring a lot of enthusiasm and skill to the club."
Mills, meanwhile, turned down offers from London Broncos to sign a new two-year deal.
He said: "I had a couple of offers and there was a good chance I was going to London. But in the end I felt Widnes were moving forward with the squad they're putting together and I am very happy to stay."
Widnes are in the midst of a massive overhaul after releasing 13 players after surviving relegation.
