This player possibly has multihack. While playing against him in his gameplay I encountered signs of wallhack and aimbot. As a proof you can see that on CS-LR4 he has only 49.12% accuracy and at the same time he has 83.26% HSKR. Moreover, on SRR-61 he has about 50% accuracy and over 80% HSKR and on P226 he has 40% accuracy and over 60% HSKR.
