Olof Kajbjer Gustafsson (born 31 January 1992),[1] better known as olofmeister, is a Swedish professional Counter-Strike: Global Offensive player for FaZe Clan.

In H2k, Gustafsson played with Joel "emilio" Mako, André "keiz" Carlsson, John "wenton" Eriksson, and Hugo "huggan" Lopez.

[2] Gustafsson quietly began his Counter-Strike: Global Offensive career in Absolute Legends[3] and H2k[2] without garnering much attention.

[15] During one of the games in this tournament against Team Dignitas, on the map Overpass, he gained widespread attention by defusing the bomb milliseconds before a Molotov could kill him, securing match point.

[19] The incident became infamous in the CS:GO community where Gustafsson and the map Overpass were nicknamed "Boostmeister" and "Olofpass" respectively.

[20] Following the event, Gustafsson considered leaving Fnatic and the game all together,[21] but wound up staying after a successful run at the ESEA Invite Season 17 Global Finals.

In August, Fnatic became the first team to win two consecutive Major Championships in a row, as they were crowned champions of ESL One Cologne 2015.

[31] On 5 March, Gustafsson and Fnatic won the IEM Katowice World Championship 2016, beating Luminosity Gaming 3–0 in the finals.

[40] In May 2020, Gustafsson announced that he will take an indefinite break from Counter-Strike and FaZe Clan, citing in a statement that he had become "increasingly fatigued" and "losing [...] motivation".

[41] On 28 October, Gustafsson returned to FaZe Clan's starting lineup as a stand-in, upon the departure of Nikola "NiKo" Kovač.
