Despite the currently collected LHC datasets not seeming to show signs of easily observable physics beyond the Standard Model, there remains a number of areas still to be explored. One of these areas is the search for long-lived particles, typical signatures of Dark Sector models. These searches most often rely heavily on non-standard reconstruction within the ATLAS experiment. Standard reconstruction relies on the particles being promptly produced - or close to promptly produced for b-tagging - at the primary collision vertex. ATLAS is now carrying out a wide range of searches for long-lived particles whose decay lengths extend from slightly beyond typical B-hadron decays lengths (few mm) to several meters with decays within the muon spectrometers. A short overview of some recent such searches will be presented.
