I just got a new set of boxes of the Nexus Steel Heroes 1/500 mechs. Nexus Editrice was an Italian company that acquired the Atlantic brand from which these models were made before. In turn, nexus was bought and became a subsidiary of Italeri.
Each box comes withn 5 mechs, 2 of a large bidel mech, 2 of a medium sized bipedal mach and one large "chicken" walker. Weapons/arms are interchangeable and customizable.
More on these soon:)
