As many may know, a Calcinite is required to research melee weapons in TFTD.
Unfortunately these aliens are so rare that you may well play an entire game without ever seeing one (or if you do, you see them extremely late with mixed race terror missions).
Because this is true, and because the Calcinite research gate before you could reverse engineer the melee weapons always struck me as being completely arbitrary, I propose adding an option that allows for direct research of the melee weapons.
Also perhaps Calcinite autopsies from interrogated Medics should count as completing the research of Calcinites for the purposes of unlocking melee weapon research in the base game.
