NGC2070, in the LMC, hosts the strongest star forming region in the Local Group and also the best laboratory to study the evolution of massive stars. However, disentangling the core of the cluster, where the most massive stars are formed, is not a straightforward task. In 2018 the narrow-field-mode (NFM) for MUSE was commissioned (matching the HST spatial resolution, approx. 70 mas), and opened an outstanding gate in the analysis stellar crowded fields. Based on a mosaic of 10 MUSE NFM fields in NGC2070, we introduce the first homogeneous census and preliminary analyses of the R136 cluster massive stellar content. Our first results aim to (i) disentangle and analyse the WR and O-type population in NGC2070, (ii) study the formation and evolution in the upper-part of the Hertzsprung--Russell diagram (50-300 Msun), (iii) map the interstellar medium composition and kinematics around the most massive stars and (iv) explore binary fraction/stellar variability.
