The Steam Workshop makes it easy to discover or share new content for your game or software. Each title might support slightly different kinds of content in their Workshop, so it's best to check out the official documentation for more details on what can be created and shared in that area.
When you find content under the Ready-to-Use Items tab you wish to add to your game, click the 'subscribe' button. In most cases the content will be automatically available the next time you launch the game. But some products require that you go into a dedicated area of the game or software to activate or access the new content.
These are the Steam Workshop features utilized by Take On Mars:
Items posted in this Workshop under the Ready-to-Use Items
tab are ready for immediate use. Click the Subscribe button on the detail page for the item and it will be available when you start Take On Mars.
Accepted items from the Workshop are made available for purchase or can be unlocked within Take On Mars.
Item Creators Can Earn Royalties
Items from this Workshop that are accepted for sale will pay the creators a split of the revenue if that item is sold for a fee.
