Just Cause 3's second sizeable add-on introduces an all-new, commendably punchy mech as part of the Air, Land and Sea expansion pack, which is coming to season pass holders on June 3rd with a wider release from June 10th. Mech Land Assault follows on from Sky Fortress, March's expansion that brought with it a jet-powered wing suit and all sorts of acrobatic possibilities. The new add-on also includes a new landmass to explore with the island of Lacrima being added to the already pretty expansive playground of Just Cause 3.
