Viper's Ace Seminar is a verbal tutorial given to the player by Viper, one of the members of Bone Arrow Squadron, during Campaign missions 3, 4, and 5 of Ace Combat Infinity. While the first two missions in the Campaign directly taught the player how to fire on aerial enemies and use Tactical Datalink, Viper's Ace Seminar teaches the player how to fight ground targets as well as how to effectively perform in Online Co-Op Missions.
