Elimination Chamber (2015) (also known as No Escape (2015) in Germany) was a professional wrestling pay-per-view event produced by WWE. It took place on May 31, 2015, at the American Bank Center in Corpus Christi, Texas. It was the sixth annual Elimination Chamber event, and the first to take place in May. In addition to being shown on the WWE Network, the event aired in many countries via traditional pay-per-view outlets.In some countries, like the United States, it was shown live exclusively on the WWE Network.
Seven matches took place at the event, with one match on the pre-show. The event was the first to feature two Elimination Chamber matches, including the first ever tag-team Chamber match. In the main event, Dean Ambrose defeated Seth Rollins by disqualification in a singles match for the WWE World Heavyweight Championship; Ambrose therefore did not win the championship.more info on wikipedia
