Ubisoft CEO Yves Guillemot has explained the delay in releasing another 'Splinter Cell' game.

It has been over five years since 'Splinter Cell: Blacklist' and Guillemot has explained that they don't want to unleash a follow-up unless it is complete "different" to the other games.

He also claimed that the success of the 'Assassin's Creed' franchise has meant the firm has been more focused on those games than 'Splinter Cell'.

He explained: "When you create a game, you have to make sure you will come with something that will be different enough from what you did before.

"Last time we did a 'Splinter Cell', we had lots of pressure from all the fans saying, 'Don't change it; don't do this; don't do that.' So some of the teams were more anxious to work on the brand.

He added to IGN: "Now there are some things and some people that are now looking at the brand; taking care of the brand. At one point you will see something but I can't say more than that.

"Also because of 'Assassin's Creed' and all the other brands taking off, people wanted to work on those brands more. so we have to follow what they like to do."

While it has been half a decade or more since fans have seen Sam Fisher, the protagonist in 'Tom Clancy's Splinter Cell' was most recently featured in 'Ghost Recon: Wildlands'
