We present an X-ray tour of the 30 Doradus star-forming complex in the Large Magellanic Cloud using high-spatial-resolution X-ray images and spatially-resolved spectra obtained with the Advanced CCD Imaging Spectrometer aboard the Chandra X-ray Observatory. R136, the central massive star cluster, is resolved at the arcsecond level into over 100 X-ray sources. Two orders of magnitude of scatter in LX/Lbol is seen among R136 O stars, suggesting that X-ray emission depends critically on the details of wind properties and binarity. Yet the dominant X-ray feature in 30 Doradus remains the intricate network of diffuse emission created by interacting stellar winds and supernovae working together to create vast superbubbles filled with hot plasma. Through X-ray studies of 30 Doradus the complete life cycle of a massive stellar cluster is revealed.
