Gem has been signed as the exclusive UK distribution partner for THQ.
The publisher's titles were previously handled by Advantage but will switch to Gem starting with the release of Darksiders II on August 21st.
"We are delighted to have appointed Gem Distribution to work as an extension of our own Sales team to reach the UK's independent retailers," said THQ's UK & Ireland sales director Jonny Harvey.
"We were looking for a partner who will be as dedicated to our business as we are and are confident we have found this in Gem Distribution."
Gem Distribution's UK general manager Darren Houghton added: "We are thrilled to add THQ to the extensive portfolio of UK publishers represented by us. THQ's forthcoming titles including Darksiders II, Metro: Last Light and South Park: The Stick of Truth represent a major opportunity for independent retailers, we are looking forward to developing a long-term relationship with THQ."
Last month, THQ signed Koch Media as its distribution partner in Spain and Italy.
