The space rover simulation game Take on Mars (now available
via Steam Early Access) just released a major update, adding a complete integration of Steam Workshop, several new side-missions, the Workbench suite for mod-makers, and various other improvements and fixes. Billed as the 'Mars Builder' update, these changes expand the game’s universe and adds new dimensions for players to explore.
The addition of Steam Workshop to Take On Mars enables players to upload, play and share a wide range of player-created content – including new terrains, models, and scenarios created with the in-game 3D editor. To kick things off, the development team created and shared an example mod pack, which includes a new crater location, a 4WD Buggy vehicle, plus a few options for customizing the Buggy with alternative sounds, configurations, equipment (turrets), and textures.
