Question: when do the seahawks play their first season game

title: Seattle Seahawks
text: In 2002 , the Seahawks began playing at what is now CenturyLink Field . Every regular season and playoff game at CenturyLink Field since the 2nd week of the 2003 season has been played before a sellout crowd . Like the Kingdome before it , CenturyLink Field is one of the loudest stadiums in the league . The stadium 's partial roof and seating decks trap and amplify the noise and reflect it back down to the field . This noise has caused problems for opposing teams , causing them to commit numerous false - start penalties . From 2002 through 2012 , there have been 143 false - start penalties on visiting teams in Seattle , second only to the Minnesota Vikings .
