Evolution Championship Series

The Evolution Championship Series (EVO or Evo) is an annual e-sports event that focuses exclusively on fighting games. The tournament is a completely open tournament and uses the double elimination format. As with Super Battle Opera, contestants travel from all over the world to participate, most notably from Japan. The first Evolution was originally held as a Super Street Fighter II Turbo and Street Fighter Alpha 2 tournament called the Battle by the Bay. It changed its name to Evo in 2002. Every successive tournament has seen an increase of attendees. It has been held at various venues across the Las Vegas Valley since 2005.
