The year after, Def Leppard played an 11-show residency at the [[Hard Rock Hotel and Casino (Las Vegas)|Hard Rock Hotel and Casino]] in Las Vegas, Nevada from 22 March through to 13 April 2013. The residency, referred to as [[Viva! Hysteria (concert residency)|Viva! Hysteria]], featured a two-part show, with the first half featuring Def Leppard opening for themselves, under the alias "Ded Flatbird", (jokingly called the best Def Leppard cover band in the world), when they played songs they very rarely play live, going back to "Good Morning Freedom", a B-side from the single "Hello America" released in February 1980, an era usually left untouched by the band. The opening set varied each night, from playing the best hits from albums like ''On Through the Night'', ''Slang'', and ''Euphoria'', to being the entire first half of ''High 'n' Dry''. The second half, and "main event" was Def Leppard, as themselves playing their best-selling album, ''Hysteria'', from start to finish. A live album, also titled ''[[Viva! Hysteria]]'' was released on 22 October 2013. This was the first time the band had played an album live from start to finish.<ref>Mansfield, Brian.

On 11 February 2014, the band released a remastered deluxe edition of their 1996 album ''Slang'' after much delay. The album, still coveted by many loyal fans of the band, now features 30 tracks including demos, B-sides, and unreleased material.<ref>{{cite magazine|url=http://www.billboard.com/articles/news/5901144/def-leppard-slang-remastered-1996-album |title=Def Leppard Revisits Overlooked Album: 'It Went Against the Grain' |magazine=Billboard |access-date=17 April 2014}}</ref> From 23 June 2014 to 31 August 2014, Def Leppard and [[Kiss (band)|Kiss]] toured 42 cities, with one dollar per ticket donated to such military charities as [[Wounded Warrior Project]].<ref>{{cite news|url=http://downriversundaytimes.com/2014/03/22/celebrity-extra-243/|title=Celebrity Extra|last=Elavsky|first=Cindy|publisher=[[King Features]]|date=22 March 2014|access-date= 5 June 2014}}</ref> Def Leppard contributed one song, "[[Helen Wheels]]", to the [[Paul McCartney]] tribute album ''[[The Art of McCartney]]'' released on 18 November 2014. Joe Elliott also contributed another track, "[[Hi, Hi, Hi]]". At certain recent points in time the band had projects, such as a cartoon and a documentary, in development. However, these projects seem to have been shelved indefinitely. The band had originally planned to do another residency in Las Vegas, this time in honour of ''Pyromania'' (called ''Viva! Pyromania''), but due to the "Heroes 2014" tour with Kiss, and the recording of their new studio album, the project had been pushed back indefinitely.<ref>{{cite magazine|url=http://www.billboard.com/articles/news/5840318/def-leppard-viva-pyromania-residency-las-vegas-new-studio-album-2014 |title=Def Leppard Plots 'Pyromania' Residency In Las Vegas; New Studio Album In View |magazine=Billboard |access-date=27 June 2014}}</ref><ref>{{cite web |url=http://www.deflepparduk.com/2014newsjan84.html |title= Vivian Says Pyromania Residency Will Not Happen In 2014 |publisher=deflepparduk |access-date=27 June 2014}}</ref> The new album was originally planned to be an EP, but the set-list increased to 15 songs by June 2014.<ref>{{cite web |url=http://ultimateclassicrock.com/phil-collen-delta-deep-def-leppard/ |title=Phil Collen Talks Delta Deep Side Project, Progress on New Def Leppard Album |publisher= Ultimate Classic Rock |date= 16 June 2014 |access-date= 15 November 2014}}</ref> The album was released on 30 October 2015 with a tour following.<ref>[http://www.virginmedia.com/music/news/story/2014/06/10/def-leppard-plan-new-album-and/ "Def Leppard plan new album and UK tour"].
