ASSASSIN'S Creed Unity has been a huge success despite its disastrous launch.
Over time, Ubisoft patched the issues and fixed the game.
And despite the complaints the title has sold by the bucketload.
Ubi announced that Unity and Xbox 360 and PS3 sister title AC: Rogue have shipped 10million copies collectively so far.
Compare that to the previous year's Assassin's Creed, Black Flag, which took five more months to sell 11m.
Company boss Yves Guillemot has admitted there were some issues with Unity's launch but the next game coming in 2015 will benefit from its new game engine.
He said: "Each time there's a new transition of consoles, we try to create engines that take full advantage of the capacity of those consoles.
"In the case of Unity, we had to redo 100 per cent of the engine. So when you do that, it's painful for all the group... and everything has to be recalibrated.“Next fiscal year we will launch a new Assassin's Creed game based on the same technology that powered Unity.”Yves Guillemot, Assassin's Creed boss
"With this game, a few things were not perfect when the game was launched. But the engine has been created, and it's going to help the brands to shine in the future.
"Next fiscal year we will launch a new Assassin's Creed game based on the same technology that powered Unity.
"We are very confident that the experiences learned, along with the customer feedback, will help us take Assassin's Creed to the next level of quality and innovation."
Meanwhile, Ubisoft noted it had now shipped 10m copies of open-world hackathon Watch Dogs.
Watch Dogs holds the record for the biggest launch of a new game series in Europe and the second-largest launch in the US behind Destiny, which also holds the global record.
"In 2014, Ubisoft offered gamers the most diversified line-up in the industry," Guillemot continued.
"As a result we achieved a third-quarter performance that was well above target and we expect to generate a record level of free cash flow for 2014-15.
"We are now capitalising on the investments we have made over the past several years to further develop our creative strengths, boost our marketing impact and extend our digital footprint.
"Our performance is all the more impressive given that it is wholly the result of Ubisoft's teams.
"Each of these successful games was developed by our in-house studios and we own our brands, which means that our destiny is in our own hands and we are internalising the value created for our shareholders."
