  We present an overview and a status report of HYPERMUCHFUSS (HYPER velocity
or Massive Unseen Companions of Hot Faint Underluminious Stars Survey) aiming
at the detection of a population of high velocity subluminous B stars and white
dwarfs. The first class of targets consists of hot subdwarf binaries with
massive compact companions, which are expected to show huge radial velocity
variations. The second class is formed by the recently discovered
hyper-velocity stars, which are moving so fast that the dynamical ejection by a
supermassive black hole seems to be the only explanation for their origin.
Until now only one old hyper-velocity star has been found, but we expect a
larger population. We applied an efficient selection technique for hot
subdwarfs and white dwarfs with high galactic restframe velocities from the
\emph{SDSS} spectral data base, which serve as first epoch observations for our
campaign with the ESO VLT and NTT in Chile, the 3.5 m telescope at DSAZ
observatory (Calar Alto) in Spain and the WHT on La Palma. The survey is
nearing completion and provides us with promising candidates which will be
followed up to measure their RV-curves to uncover massive companions or prove
their nature as HVS.
