Things slowly build up on game day for more than an hour before the first play.
The Alamodome starts out quiet with just a few people moving around.
Players, coaches, team staff and members of the media slowly fill in.
As game time approaches, there is the national anthem and then players take the field.
And as the San Antonio Commanders took on the Salt Lake Stallions on Saturday night, the Alamodome roared as players holding the Commanders flag and Texas flag charged onto the field.
