UK retailer Game has sold its entire Multiplay Digital division to game engine maker Unity for £19 million ($25.2 million).

The deal will see Unity shell out £17.1 million ($22.7 million) upfront, with the remaining £1.9 million ($2.5 million) being held in escrow for another 19 months.

Multiplay Digital is the retailer's online game server hosting business. It currently supports a number of major titles including Titanfall 2, Day Z, and Killing Floor 2.

The Multiplay unit originally consisted of two different divisions: Digital and Esports & Events. Game has transferred the latter to another wholly-owned subsidiary, and says it remains "committed" to the Esports & Events business.

Game had already outlined plans to sell Multiplay Digital back in August, with the firm looking to raise cash and strengthen its position in a tough retail climate.

"This transaction is a significant strategic step forward for Game Digital," said company CEO Martyn Gibbs."By divesting Multiplay Digital we simplify the group and focus management on accelerating development plans to fully capitalize on the strong growth potential in our exciting and growing eSports activities, including Belong.

"We are delighted to have transacted with such a strong new owner for our Multiplay Digital business and its highly talented team, and we now look forward to further developing Game Digital as we seek to combine multichannel retail, events and eSports."
