We construct the ambitwistor pure spinor string in a general type II supergravity background in the semi-classical regime. Almost all supergravity constraints are obtained from nilpotency of the BRST charge and further consistency conditions from additional world-sheet symmetries. We also discuss the case of $AdS_5\times S^5$ background.

The spectrum of the bosonic ambitwistor string revisited
The bosonic ambitwistor string spectrum is confined to the massless sector and contains the dilaton, metric, Kalb-Ramond field plus an extra vector, but is non-unitary.
