This set opens access to the fifth class of characters "Mehromantka", which can call to the aid of destructive robot "Zhestocus". In addition to the new class, by purchasing this add-on, you also get access to all the bonuses that were previously available only in the Borderlands 2 Premiere Club Pack - Gearbox Gunpack, Golden Key and Vault Hunter's Relic.
