I absolutely adore UFO: Aftermath, but since you never really see Council of Earth troops, it's hard to tell what they'd look like. Even still, I've started working on my own custom army - Phoenix Company, straight from UFO itself!
They're based on a mixture of Astra Militarum and Spellcrow Shock Troop parts, plus whatever else is relevant at the time. So far, I've only created two (which will serve as the basis for the rest), but more are on the way every so often!
They'll be painted later on, too - I want to get better and make sure that I have enough skill to accurately re-create the spec ops armour from the original game, so I'll keep putting practice in first.
They still need some touch-ups, but they're looking good so far!
