  The FELIX collaboration has proposed the construction of a full acceptance
detector for the LHC, to be located at Intersection Region 4, and to be
commissioned concurrently with the LHC. The primary mission of FELIX is QCD: to
provide comprehensive and definitive observations of a very broad range of
strong-interaction processes. This paper reviews the detector concept and
performance characteristics, the physics menu, and plans for integration of
FELIX into the collider lattice and physical environment. The current status of
the FELIX Letter of Intent is discussed.
