How to unlock the Minor Skirmish achievement in Dance Central 3 - Definitive Guide
This needs two people or a fake person.
Select Crew Throwdown from the Dance menu and when it asks you to choose your crews, have only one person step up for each crew. It might be wise to select only "Make your Move" and "Keep the Beat" from the options menu for the other achievements related to those modes. Once you finish the Throwdown, this achievement will unlock.
