Guidelines for X-COM: UFO, Enemy Unknown…for HoTT!

My thinking is pretty much the same as yours Paddy.

Etherials: any hooded Medieval monks, and even some hooded Druids, would fit well,
                with black faces and painted coppery-orange with scratch-built rayguns.

Sectoids: their Cyberdisc Aerial Terror Units have two possible options…I happen
                to have some cheap blue tinted round ‘John Lennon’ type sunglasses,
                or use a stout pair of scissors to cut out the bottoms from beer cans.
                (And I have a awful lot of those!)

Floaters: I also have many boxes of (unpainted) plastic 20mm ancient figures.
               Cut the legs off any cloaked figures and glue them onto necklace beads.
               Thracians with modified cut down hats work well.
               (There’s no reason why some Aliens can’t be taller than X-COM soldiers)
               And for their Reaper Biting Terror Units, I happen to have a Risk Star Wars
               game, with lots of plastic ‘Rancor’ figures. I plan to cut their arms off and
               add paper painted silver to their legs and head to represent their armour.

Snakemen: their Chryssalid Parasitic Terror Units are easily represented by the
                  “Alien” from the film of the same name, with their back spines, tails
                  and the back of their long skulls removed and modified.

Mutons: yes, these are a bit of a problem. I’ve seen other wargamers use Marvel ‘Hulk’
              figures for these. But since in the more modern versions of the X-COM PC game
              they look more like Warhammer figures with impossibly large shoulder armour,
              perhaps these would do.
              Their Celatid Acid Spitting Terror Units are just blobs of purple milliput.

For Early X-COM in uniforms I’m going to use WWII soldiers with blue berries.
Not entirely authentic I know…but they can then double-up as U.N.I.T troops
for fighting my Doctor Who Daleks.
