Currently working on creating a Playable Devourer faction! Check it out early footage:


So technically there are two factions, one optimized for AI use and one designed for a Player.
As explained Devourers are Parasitic organisms that spread from world to world eating everything in sight. In order to make them playable, I really wanted this to be shown in its gameplay.
As you see, Food is the only resource. However this faction has no farms or cows to produce. In order to obtain food you will have to actively hunt for food. You can hunt native creatures or Valkyries themselves. Only Valkyrie infantry count. Vehicles, Drones, and Structures explode on death.
The concept of giving devourers resources when they eat your units is actually not new. This was already in place in the AI version, however it was not food just a standard resource. So yes when you are playing as the Valkyries, the more units you loose the more resources the Devourers get.
You can Harvest Trees with worker type devourers. This gives you the resource "Organic" Using Lua, Organic resource is automatically converted into Food at the rate of 10 Organic -> 1 Food. Trees are a weak source of food. Since organic is not used for unit production, MG does not display it

Thinking of adding the ability to cannibalize your own Devourers for an emergency food source.
Also another new tweak for player version is that Devourers build structures from Morphing, not building. And yes they too require food.
A unit hierarchy is still needed. Currently all devourer types are available from beginning.
