The All-weather MUse Supernova Integral field Nearby Galaxies (AMUSING) survey is a collaboration that utilises sub-optimal conditions to obtain MUSE observations of supernova (SN) host galaxies. Its aim is to constrain the progenitor properties of SNe through analysis of their environments. Every semester AMUSING focuses on a distinct science case, and thus far we have compiled more than 700 SN host-galaxy observations. With such data additionally being of use for emission-line studies, we have published more than 30 AMUSING-based articles. In this contribution, I will first summarise AMUSING, its strategy, statistics and scientific highlights. I will then focus on results of a project aiming to constrain core-collapse (CC) SN progenitors - those arising from massive stars. We use a sample of MUSE-observed host galaxies of around 100 CCSNe. Analysing all HII regions within the FOV, we compare the CCSN hosting regions with all other regions within the sample. We find that the CCSN HII regions have abundances offset to significantly lower metallicity than all other HII regions. This result could be explained by a strong metallicity effect on the 'explodability' of massive stars, or it could imply that star formation at low metallicity is significantly different to that at higher abundance. We discuss these possibilities and others, highlighting the significant impact they would have on our understanding of massive star formation and death - whichever is the underlying cause.
