Aliens of London: The Beta, in the campaign, have an accent that sounds South African or New Zealander, with a bit of Russian and Middle Eastern mixed in. And even the Goo are just fighting for their survival. Is a Crapshoot: If we ignore the Goo trying to nom everything around this is actually averted: humanity lives perfect lives with their intelligent creations. This is also why the shroud has such long build times and pays upfront. They have a higher resource income rate and this is extremely explosive, to the point of being able to virtually spam out units and structures as much as the player can micromanage not his resources but his ludicrous level of production buildings. The Shroud are an incredibly aggressive faction, and the most advanced in playstyle, requiring knowledge of all prior factions. However this power comes at a price of immobility: everything must be connected to the central headquarters for power, which means expanding outward with the humans is a slow process, and power lines can be left vulnerable. The Humans are the elitist faction, with weapons technology more advanced than the Beta and perhaps even the Goo, with intelligent walls, specialised defences and powerful combat drones. Beta units rely on mobility and firepower, they can cover ground quickly and many of them can shoot on the move, but their garrisonable walls and defences mean they can hold ground well too.
Playing most like a conventional RTS faction, the Beta offer modular base structures that can be customised through attached buildings.
Likely one of the most mechanically unconventional RTS factions ever devised, the Goo have no base-building or standard resource gathering to speak of: Mother Goo grow and duplicate when exposed to catalyst and rapidly break down enemy units and structures on contact, or can form smaller, more specialised units using their mass. The Goo is a spammer (surprised?), and extremely mobile, able to ignore terrain completely.
