High luminosity data collected at a center-of-mass energy of 7 TeV at the Large Hadron Collider by ATLAS experiment has allowed it to search for supersymmetry (SUSY) and SUSY signatures with an unprecedented statistical precision and mass reach. We here present searches for different signatures in many channels, including jets plus missing transverse energy E_T^(miss), optionally with leptons, di-leptons plus E_T^(miss), B-jets plus E_T^(miss) as well as electron plus muon resonance and slow meta-stable particle searches
