IceFrog is a game designer, known for being the longest-serving developer of the Warcraft III custom mod Defense of the Ancients. He is currently employed by Valve Corporation as the lead designer for Dota 2, the stand-alone sequel to the original mod, a position for which he was hired in 2009. IceFrog's involvement with DotA began in 2005, when he inherited the reins of the dominant variant entitled DotA Allstars from Neichus who himself inherited it from Steve "Guinsoo" Feak. IceFrog is noted for his continued anonymity, having never publicly disclosed his actual name. He did however reveal that he was 25 years old on his blog on February 3, 2009.[non-primary source needed]
