  In the recent years the NA49 experiment has collected data on Pb+Pb
collisions at beam energies between 20 to 158 AGeV with the objective to cover
the critical region of energy densities where the expected phase transition to
a deconfined phase might occur in the early stage of the reactions. In this
contribution the energy dependence of various hadronic observables is
presented. These include m_t- and rapidity- distributions, particle ratio
fluctuations, as well as HBT radii.
