RadiumFalcon, also known as Radium and ToxicBlaze [on forums], is an active community member, mapper, and NUMA reviewer. He joined the community in June 2008. He enjoys having a distinct mapping style that has been compared to that of blackson, toasters, and shortshift. Certain community members named him as one of the most talented new mappers of 2008. He has two featured maps, Sensual Silence and Anarchy in Guatemala.
As of January 2009, he also frequents the N IRC channels. As of August 23, 2009, Radium expressed that he could not deal with the immense levels of faggotry in #moa and would no longer chat in #moa. Around this point, RF tried his hand at speedrunning and can now be found in #n-highscores.
