The accessible energy range is 10¹⁵-10¹⁸ eV. In this contribution, a description of the array and main results obtained so far are presented. A current update of the array includes the deployment of scintillation stations, radio antennas, as well as optical stations. The deployments of these optical stations are the first step towards Tunka-HiSCORE, a wide-angle, large field-of-view gamma-ray telescope. © 2013 Elsevier B.V.en© 2013 Elsevier B.V.
