The project Probing Extreme PeVatron Sources (PEPS) aims at measuring the most energetic gamma rays from our Galaxy in the energy range between 10¹⁵eV and 5x10¹⁶ eV, opening a new energy window for multimessenger astroparticle physics. PEPS will consist of an array of 10 km² placed in the southern hemisphere, at the location of the Pierre Auger Observatory. It will be built in two phases, with the first phase covering a surface of 2 km². The location offers an excellent view of the Galactic Plane and the Galactic Center while taking advantage of the existing infrastructure of the Pierre Auger Observatory. The design is based on an array of water-Cherenkov particle detectors with a horizontal segmentation of the optical volume into two. We present the performances of two prototype detectors that are functioning in the field. The science case for PEPS will be presented.
