No Limit (EP)

[5] Monsta X held a comeback showcase on Universe to introduce the EP alongside its title track on November 18.

[8] On that same day, Monsta X showed up on MBC's Idol Radio hosted by members Hyungwon and Joohoney.

[10] On December 1, Monsta X wrapped up their official activities for the comeback on Naver Now's Midnight Idol hosted by members Kihyun and I.M.

[1][2] Reviewing the EP for NME, Carmen Chin showed that it upholds the group's ambition "to unashamedly evolve into musicians who break barriers" and it delivers "quality music shaped by the very hands of Monsta X", with all the tracks "flaunt[ing] either writing or production credits from two or more members of the group at a time".

[2] Divyansha Dongre, writing for Rolling Stone India, wrote that "Rush Hour" captures the group's "vocal prowess and mastery in the hip hop-EDM sphere", adding that its confidence-inspiring lyrical arrangement "effortlessly encapsulates the group's strengths that contributed to their dynamic growth since their debut in 2015".
