A free update is being added to Cities Skylines tomorrow which will add mod support to the Xbox One version.
It won’t be quite as free as the PC version, with developers vetting the content first before allowing it to be used on the Xbox One version. These mods will have been ‘curated, tested, and ready to drop right into your cities.’
Paradox have also stated that they hope to ‘see about keeping this content growing’ so expect this mod program to continue evolving in the weeks and months to come. All as free updates.
There will also be a free content update to allow players to host sports teams on March 6, in addition to all DLC in the Season Pass, including the Content Creator Pack which is a series of buildings created by community members.
