As the name suggests, Patch 1.1: Elemental Destruction is all about ways to unleash different elements upon enemies to bring about their ruin. The update's newest weapons are the plasma flak cannon and bio injector, however even older weapons can get new modifiers to change their damage type. The additional weapon modifiers include thermal, flaming thermal, bioactive, virulent bioactive, electrical, charged electrical, beam, laser beam, microplasma, and emissive microplasma. Even grenade launchers have gotten love with new ways to throw out explosives in a spread or cluster.
Patch 1.1 also adds five dynamic encounters, two new ARES job boards, and a hardcore version of Kanaloa the Destroyer.
