For the 2015 season, Archie, GoNy, and QTV rejoined their former teammates after leaving the Saigon Jokers, and the team renamed to the Boba Marines.

Afterwards, star players Ren, Levi, Slay, and Sergh joined the Marines as top, jungle, AD carry, and substitute support respectively.

The team received new sponsors, Gigabyte Technology and Adonis Icyber Gaming, and renamed to Marine Esports.

Despite their placement, the Marines' performance secured Vietnam a guaranteed group stage seed at the 2017 World Championships[1] and an additional spot in the GPL.

[2] The Marines were placed in Group B at the 2017 Worlds Championships, where they initially tied for second with Fnatic and Immortals,[3] but had the highest seed going into the tiebreaker matches due to them having the shortest combined victory time.

[8] The Marines finished third in the 2018 VCS Spring Split group stage with 9 wins and 5 losses, qualifying for playoffs, where they defeated Young Generation 3–1 in the quarterfinals and UTM Esports 3–1 in the semifinals.

In the semifinals they swept Lowkey Esports 3–0, moving on to face Team Flash in the grand finals, who they beat in a 3-0 fashion.

GAM Esports qualified for the 2019 World Championship, where they were placed in group B alongside FunPlus Phoenix, J Team, and Splyce.

Despite securing a spot at the 2020 World Championship, GAM Esports and Team Flash could not attend the event due to the pandemic.
