Shrewsbury's new signings shared the goals as they ended a run of four straight defeats with a convincing win over a lacklustre Morecambe side.
Loanee Asa Hall marked his debut with a goal on four minutes although Shwan Jalal should have done better to save his header from Marc Pugh's cross.
And Guy Madjo, a capture from Crawley, scored with a fierce left-foot low drive on 31 minutes on his home debut.
Morecambe's best chance was Adam Yates' late long-range shot that hit the post.
