Here we combine VLT/MUSE Guaranteed Time Observations of the Hubble Deep Field South, Ultra Deep Field, COSMOS, and several quasar fields with other publicly available data from VLT/VIMOS and VLT/FORS2 to construct a catalogue of HeII${\\lambda}$1640 emitters at ${z\\sim2}$. The deepest areas of our MUSE pointings reach a ${3\\sigma}$ line flux limit of 3.1${\\times}$10-19 erg/ s/ cm$^2$.
