RadiumFalcon, (also known as Radium and RF), is an active community member, mapper, and an ex-reviewer. He joined the community in June 2008. He is proud of the fact he has created his own distinct mapping style which is almost immediately recognizable as "The Falcon's". RadiumFalcon's archive contains over 200 maps as of April 26th, 2010. RF has released no mappacks because he thinks they do not receive enough attention. Certain community members named him as one of the most talented new mappers of 2008. He also brought his cousin, mahi_mahi, into the community in July 2008 (now a prominent community member). He has four featured maps, Sensual Silence, Anarchy in Guatemala, ASASAS and sweet sweet elixir. Radium plans on staying on NUMA for a long time, as it is his favorite creative output.
As of January 2009, he also frequents the N IRC channels.
RF was partly responsible for the the Stacey Incident.
