[5][6] He has played for Virtus.pro, AGAiN, Universal Soldiers, ESC Gaming, Frag eXecutors, Vitriolic, Wicked eSports, Meet Your Makers, and Pentagram G-Shock.

Kubski is also considered to be very good at Counter-Strike 1.6's in-game movement,[8][9] which makes him difficult to counter.

NEO wandered around some Polish teams before joining Pentagram G-Shock, along with what has been called the "Golden Five" lineup of Wiktor "TaZ" Wojtas, Łukasz "LUq" Wnęk, Mariusz "Loord" Cybulski, and Jakub "kuben" Gurczyński.

Even though there were no Valve organised tournaments in 1.6, generally, ESWC, CPL, WCG, and IEM are considered to be a CS 1.6 major.

They had a few decent results after this, including a semifinals finish at PGL Major Kraków, and a second place appearance at EPICENTER 2017.

[24] Following this, Virtus.pro ended the longest standing roster in CS:GO history by replacing Wiktor "TaZ" Wojtas with Michał "MICHU" Müller.

[26] His individual form continued to drop off since 2017, but he was signed by FaZe Clan, replacing Dauren "AdreN" Kystaubayev.

[27] With FaZe, NEO came second at BLAST Pro Series: Los Angeles, but at the major, he would once again exit in the group stage.
