  The Tarantula Nebula (30 Doradus) is the most important star-forming complex
in the Local Group, offering a microscope on starburst astrophysics. At its
heart lies the exceptionally rich young stellar cluster R136, containing the
most massive stars known. Stellar winds and supernovae have carved 30 Dor into
an amazing display of arcs, pillars, and bubbles. We present first results and
advanced data processing products from the 2-Ms Chandra X-ray Visionary
Project, "The Tarantula - Revealed by X-rays" (T-ReX). The 3615 point sources
in the T-ReX catalog include massive stars, compact objects, binaries, bright
pre-main-sequence stars and compact young stellar (sub)clusters in 30 Dor.
After removing point sources and excluding the exceptionally bright supernova
remnant N157B (30 Dor B), the global diffuse X-ray maps reveal hot plasma
structures resolved at 1-10 pc scales, with an absorption-corrected total-band
(0.5-7 keV) X-ray luminosity of $2.110\times 10^{37}$ erg s$^{-1}$.
Spatially-resolved spectral modeling provides evidence for emission lines
enhanced by charge-exchange processes at the interfaces. We identify a
candidate for the oldest X-ray pulsar detected to date in 30 Dor, PSR
J0538-6902, inside a newly-resolved arctuate X-ray wind nebula, the Manta Ray.
The long time baseline of T-ReX monitored dozens of massive stars, several
showing periodic variability tied to binary orbital periods, and captured
strong flares from at least three low-mass Galactic foreground stars.
