RadiumFalcon, (also known as Radium and RF), was an active community member, mapper, and an ex-reviewer. He joined the community in June 2008. He is proud of the fact he has slowly synthesized his own mapping style; his maps are quite distinct in aesthetics and game-play. 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 six featured maps, Sensual Silence, Anarchy in Guatemala, ASASAS, Illusions, the powerless rise and sweet sweet elixir. Radium plans on staying on NUMA for a long time, as it is his favorite creative output.
In 2011, RadiumFalcon has become inactive, for the most part. His is slowly working on a ten-episode map pack, his very first.
RF was partly responsible for the the Stacey Incident.
