2012 MLG Pro Circuit Summer Championship is the final event of the 2012 MLG Summer season. As with previous MLG Pro Circuit events, the tournament has two preliminary stages - a Group Stage for the highest seeded players and a double-elimination Open Bracket. However, the Group Stage has a new name and format: double-elimination Group Play replaces the round-robin Pool Play from previous Championships. The Open Bracket and Group Play are conjoined in a culminating double-elimination Championship Bracket.
