In August 2012, mouz announced the British CS: GO squad, which included Mx, RattlesnK, Hughsy, RE1EASE and pt. In October, Team xXx was signed: approx, nex, stavros, strux1 and Troubley. In December, the British left the organization, and karrigan and zonixx replaced stavros and strux1. After the changes that took place in 2013, the squad did not settle down: in the cadiaN and cLy team, they replaced crisby and gob b. Then the composition continued to shake, some players were replaced by others. The latest changes occurred in December 2015, when Spiidi changed gob b. After that, the team managed to stabilize the roster, but to show a good result on the pro scene for them is still not an easy task.
