The wait is over! Rock the Cabinet 2017 is finally here and this year, we’re setting our sights on the very popular Co-op mode. Last year we asked players to design their own Mutators and create a brand-new custom Mutation. This time around, we’re challenging our talented map-making community to create, test, and polish their very own Co-op Mission. If you take first place, we’ll incorporate your winning entry into an all-new Co-op Mission that anyone will be able to play.
To give you guys the tools you need, we’ll be adding a template map that will allow you to set up your Co-op Mission with Raynor, Kerrigan, or Artanis. You’ll be able to edit and publish your map to the public for testing purposes. We’ll have more details about this template map when it’s released.
Additionally, we’ve prepared the following co-op guidelines document describing some of our design philosophies when building Co-op maps. By following these guidelines, you will be increasing the likelihood that you'll receive positive marks from the judges who review your entries. Though these are not requirements, we strongly suggest you keep them in mind when creating your map.
