In September 2010, Boxer began playing high level "StarCraft II" games against other pro gamers as Terran under the username ManofOneway, but has switched to SlayerSBoxeR since he announced his return. He is now playing "StarCraft II" at a professional level and has made it to the Round of 4 in GSL (GOMTV Global StarCraft II League) Open Season 2, where he lost 0–4 to NesTea. However, he would not fare as well in following seasons, even dropping to Code A (the lower GSL League) in March 2011.
