Pre-4 Mission (Episode 1–2)

For the Pre-4 Mission, each contestant chose a song and formed a 4-member group to perform a single stage. The ranking on Voice Check-in has a big impact for this mission and if the song has filled with four members, the lower placed contestant must choose another song. Although it is a group mission, the evaluation is individual, and the most voted team member by the judges becomes the top tier and has the right to select the lower tier from the team.[6]

2 vs 2 Rival Mission (Episode 3–5)

In 2 vs 2 Rival Mission, contestants formed a duet and competed against another duet. The top tiers from Pre-4 Mission can partner with anyone in all sections (Top, Middle and Low), the same matching rule applies with middle tiers but only to sections M and L while low tiers can only team up in their respective section. Another rule is the low tier contestant cannot refuse the top tier contestant's offer to form a team and if picked by more than two then the contestant could choose his partner. The duet with a higher judge score wins and the losing team is a candidate for elimination.[7]
